Definitions
- This invention relates to lasers and in partic- ular to laser systems suitable for medical applica ⁇ tions such as selective photother olysis.
- targeted tissues are heated by laser light, the wave length of which is selected to be specifically absorbed by the targeted tissues.
- the laser pulse duration is tailored to the size of the target. Tissues surrounding the targeted structures are spared.
- thermal diffusivity is added there is a pulse duration criterion and the energy must be deposited quickly to minimize heat dissipa ⁇ tion to surrounding tissue.
- selective photothermolysis heat must riot be deposited too quickly so as to exceed the boiling point in the targeted zone.
- small absorbing chromophores such as hemoglobin in blood cells are used as absorbers to treat blood vessels which are an order of magnitude larger.
- the radiation must be added at low intensities so as not to vaporize the small cells, left on long enough to heat the blood vessels by thermal diffusion to the point of denaturation and then turned off before the surrounding tissue is damaged.
- dye lasers are readily tunable to selected wave lengths by means of the choice of dye, wave ⁇ length selective filters in the cavity and the like. Further, dye lasers can provide high output energies and short pulse durations. Unfortunately, the typical dye laser pulse duration of only a few microseconds or less is too short for many applica ⁇ tions using selective photothermolysis. Dye lasers with nanosecond or shorter pulses are preferred for subcellular organelle targeting and microsecond or shorter pulses are preferred for cell targeting. However, dye lasers do not typically provide the millisecond pulses which are best for blood vessels and other small structures.
- the quenching of a dye laser after microseconds may be due to the accumulation of dye molecules in the triplet state by means of intersystem crossing from the singlet state.
- Laser action in a dye laser starts from the singlet states. Molecules which cross over to the triplet state often absorb at the laser wavelength and inhibit laser action.
- the triplet state effect has been investigated and triplet state quenchers have been reported for specific dyes. However, triplet quenchers for all dyes used in lasers have not been identified. But, even with the use of triplet quenchers, pulse durations of several hundred microseconds have only been obtained at low energy outputs of not more than a few tenths of a joule.
- a second problem that makes it difficult to generate long pulses in a dye laser is the distor ⁇ tion of the liquid amplifying medium by absorbed, conducted and convected heat from the laser excita ⁇ tion source. Such distortions are unavoidable but must be minimized for laser action to continue for milliseconds.
- a laser has been developed which is more suitable for selective photothermolysis because the laser pulse duration is adjustable to durations approaching one millisecond.
- the present laser is based on the recognition that thermal distortion in the laser medium results in changes in the index of refraction in the medium and loss of resonating modes for which the laser is designed.
- a multiple pass light amplifier which may be considered a spatially noncoherent laser, comprises a cell having a medium excitable to an energy level with net optical gain and having apertures at opposite ends of the cell.
- the Fresnel number of the cell is greater than one, distinguishing it from wave guide lasers.
- Means such as a flashlamp is provided for raising the medium to an inverted energy configuration.
- An optical system at each end of the cell images each aperture upon itself. As a result, substantially all light emanating from the aperture, within a wavelength band determined by the dye solution and any tuning element, is returned to the cell through the aperture.
- the optical system at one end of the cell allows part of the light to escape and be used.
- the resultant beam of light which passes through one of the optical systems has directional concentration to a solid angle substantially less than one sterad an, m the order of 10 -4 steradian, although that concentration is somewhat less than
- the means for imaging the aperture on itself is a spherical mirror located a distance from the aperture about equal to its radius of curvature.
- a lens is positioned between the aperture and the flat mirror. The lens is positioned at about its focal length from the aperture. The light emanating from the cell is collected by the optical system and reflected back into the cell. The light traverses the cell in a number of total internal reflections off other cell walls. The dye solution in an excited state amplifies the light rays traversing the cell.
- the gain medium has a continually chang ⁇ ing index of refraction, light rays traversing the cell have no fixed pattern and resonator modes are not established; rather, the spontaneous emission localized in a cone determined by the reimaging optics is amplified on successive round trips through the cell throughout the duration of the laser pulse.
- the power supplied to the flashlamp is provided with a variable pulse length circuit which provides for variable length pulses in the range of at least about 10 to 500 microseconds.
- the system allows for pulses of up to one millisecond duration.
- An output of at least about one joule is provided.
- Fig. 1 is an illustration of a preferred embodiment of the invention.
- Fig. 2 is an illustration of an alternative embodiment of the invention using spherical mirrors.
- Fig. 3 graphically illustrates a typical laser pulse plotted over the flashlamp excitation pulse and showing thermal distortion in the laser pulse.
- Fig. 4 is a graphical illustration of a laser pulse over the flashlamp excitation pulse in a system embodying the present invention.
- Fig. 5 is yet another embodiment of the inven ⁇ tion having a bent gain medium.
- the early termination of laser action during a long excitation pulse is considered to be primarily of thermal origin. Heat is absorbed by the solution and heat is convected from the lamp to the dye cell if the pulse is long enough. Acoustic velocities are in the order of 0.5 mm/microsecond, and with a dye cell bore of 4 or 5 mm there will be density and index of refraction gradients throughout the cell when laser pulses are longer than ten microseconds. If the gradients are very large, the result is a loss of identifiable resonating modes and quenching of the laser output.
- a laser system embodying the present invention is shown in Fig. 1. The system is a modification of a conventional flashlamp excited dye laser.
- a laser medium in the form of a dye carried by a liquid is directed through the dye cell from one end to the other.
- the medium is maintained at a uniform and constant temperature.
- a high voltage developed in a power supply 14 is applied across a flashlamp 16.
- a small simmering current may be applied from a supply 17 to the flashlamp prior to starting a pulse from the supply 14 in order to develop a significant level of ionization in the flashlamp prior to discharge.
- Light energy from the flashlamp is directed inward to the laser medium by means of a reflector 19. The energy from the flashlamp is absorbed by the laser medium and moves molecules in the medium from the ground state to excited singlet states.
- the optics at each end of the dye cell 12 are designed such that the photons travelling back and forth between the two mirrors 22 and 24 follow specific paths such "that the photons resonate in particular modes.
- the photons resonate at a common frequency and phase.
- the light between the mirrors reaches an intensity such that a measurable amount passes through the mirror 22, which is not a full reflec ⁇ tor, as a beam 26.
- the beam 26 is coherent and the divergence of that beam is very small, in the order of 10 —8 steradians.
- the laser optics must be precisely designed.
- the optics mix the resonating rays and thor ⁇ oughly homogenize the beams. Any thermal distor- tions which are induced by the flashlamp are of little consequence because there are no resonator modes.
- the rays traverse the cell and are amplified but do not follow a precise path determined by the optics. Those rays that are highly deviated as to miss the dye cell are lost.
- the homogenization is random and there is no phase relation at the wave front.
- the modes if any are randomly oriented and completely homogenized. The randomness is spatial as well as temporal. Spatial coherence is not preserved but monochromaticity can be partially pre ⁇ served with suitable wavelength selective elements.
- the medium has gain and a definite threshold and therefore is classified a laser.
- a tuning element 31 may be provided to tune the laser output within the gain curve of the dye solution.
- the tuning element can reduce the bandwidth of the beam to less than .01 nanometers and is used to match the absorption band of the target to enhance the desired physio- logical effects.
- the most effective tuning elements are those that do not depend on this spatial coherence,
- the tuning element may be an etalon, a birefringent filter or a prism.
- Fig. 2 illustrates an alternative embodiment of the invention in which the optics at each end of the dye cell are replaced with spherical mirrors 32 and 34.
- Each mirror is positioned at a distance from the aperture 18, 20 which about equals its radius of curvature R.
- Each spherical mirror reimages the aperture back on itself as do the optical systems in the prior embodiment.
- Figs. 1 and 2 do not provide the coherent radiation of a conventional laser, and their output beams diverge across a solid angle of 10 -4 steradians.
- the large depth of field obtained from coherent radiation is not required.
- the concentration of light, though not as great as with the conventional laser, is significantly greater than the one steradian obtainable with nonlaser radiation and is adequate for selective photothermolysis.
- the advantage of the present system, as applied to selective photothermolysis is that the beam is not limited by thermal distortion to a pulse duration of less than ten microseconds. Rather, pulse durations approaching one millisecond are possible.
- a pulse duration can be made variable to meet a number of different applications.
- a pulse forming network 36 is provided to generate electrical pulses and transmit the pulses to the flashlamp 16, through a relay switch 38.
- the pulse width may be selected from the range of 10 microseconds to 500 microseconds and preferably to as high as one milli- second.
- Standard plane-plane or confocal laser resona ⁇ tors show thermal effects at times in the order of ten microseconds.
- the symptom for thermal distortion is an instability in the amplitude of the laser output pulse.
- flashlamp excitation pulses have a smooth envelope and the laser output pulse closely follows the excitation pulse. If thermal effects distort the laser medium, then the laser intensity will show an amplitude fluctuation.
- Figure 3 shows the output of a laser with a standard laser configuration; the laser pulse shows amplitude fluctuations after ten microseconds. Such amplitude fluctuations are seen in all long pulse dye lasers that use standard laser resonators.
- Figure 4 shows the same laser with a laser resonator configuration according to this invention that compensates for the thermal effects; the amplitude fluctuations are eliminated.
- This system is similar to a waveguide resonator n that the sum of the focal lengths is less than 1, the optical length between the mirrors. However, it is not a waveguide resonator for the following reasons. (1) There is no restriction on the .Fresnel number of the guide. The Fresnel number is equal to a / 1 where a is the radius of the dye cell, is the -14-
- the waveguide resonator works with guides that have a Fresnel number less than one. Typical Fresnel number for the long pulse dye laser is 6 to 10 or even larger. For example, for a typical system a equals 2 mm, 1 equals 0.5 to 0.5 meters and equals .5 micrometers.
- the waveguide laser has resona ⁇ tor optics that match the free space TEM mode to some of the lower order waveguide modes such as the HE o i or HE ll oc - e - There is no such restriction in the present system. There is no unique curvature for the mirrors to go with the aperture of the waveguide as in the true waveguide laser.
- Resonating modes are absent in the present sytem, and any ray that is reimaged on the exit/entrance aperture can have net gain.
- the beam divergence is large but still less than that emanating from a guide with a given numerical aperture, or from a tube whose optical beam divergence is defined by the aspect ratio of the tube. Because of the large beam divergence, tuning elements that depend on minimum beam divergence are not effective as line narrowing elements. However, etalons are effective and linewidths to .03 Angstroms have been obtained using the present system. Birefringent filters have also been used to tune the present system.
- the present laser advantageously satisfies the criteria for selective photothermolysis.
- a dye laser emitting at 575 nm with pulse durations up to 400 microseconds has been developed for the treat ⁇ ment of cuta-neous vascular lesions such as birth ⁇ marks. Such birthmarks are caused by a high density of blood vessels close to the surface of the skin. These blood vessels can be eliminated by selective photothermolysis.
- the selective photothermolysis laser should emit at 575 nm where blood has secondary absorption maxima at least an order of magnitude larger than that of pigmented tissue of fair skin.
- the laser should emit pulses about one millisecond long to couple energy into the blood vessels which are several hundred microns in diameter.
- the vessel will then be heated to denaturation temperature without vaporizing the blood cells.
- the laser should then be turned off before tissue surrounding the blood vessels is damaged.
- a laser with variable pulse duration can be used in selective photothermolysis for a number of medical treatments other than the treatment of cutaneous vascular lesions. These include he o- stasis of bleeding ulcers, suppression of choroidal neovascularization that leads to blindness, and hemostasis after the removal of eschar in burn therapy. If exogenous chromophores can be selec- tively injected into target tissue, the principle of selective photothermolysis treatment with tunable, variable pulse duration lasers can be extended to cover many medical applications too numerous to mention.
- Fig. 5 illustrates a modification of the system of Fig. 1 which is possible with the present system. Because the primary parameter of importance is the relation between the focal length of the optical system and the distance to the dye cell aperture and not the length of the dye cell itself, a bend as shown in the dye cell 36 of Fig. 5 is possible.
