According to the laser-medium temperature equalization reflector, the radial cambered boss is combined with the notch groove of the lantern ring to form the round ring to form the temperature equalization reflector, and the problem that the laser output energy is reduced due to uneven heating of the laser medium during side-pumping of the laser medium by a semicircular diode can be solved.
Description
Technical field
The present invention relates to a kind of laser medium temperature equalization reflector of semi-circular diode side pumped solid state laser.
Background technology
In semi-circular diode side pumped solid state laser design, usually adopt the semi-circular diode side pumped laser medium structure of Fig. 4, the pump light that it sends light emitting diode shines on the laser medium, residual pump light passes through on the reflector reflected back laser medium, thereby makes solid state laser have higher light light conversion efficiency.In this version, if the designing requirement laser medium can not adopt the cooling of dispelling the heat of liquid cools mode, laser medium can only and air between form nature conduction cooling, because diode is semi-circular single side face irradiating laser medium, owing to the reason laser medium of thermal gradient can produce deformation, cause the output energy decreases of solid state laser serious, can't satisfy instructions for use.During the reflector of Fig. 4 shown in the employing, the initial value of the output energy of (90 seconds operating times) solid state laser is compared with end value and is descended 15%～20% in the regulation operating time.
Summary of the invention
Based on the problems referred to above, of the present invention at prior art laser structure employing nature conduction cooling, output energy decreases serious problems, provide a kind of and can improve body laser output energy stability, and can improve the temperature equalization reflector that laser medium is heated evenly, to solve the serious problem of prior art diode pumping solid laser output energy decreases.
The present invention realizes that the technical solution of above-mentioned purpose is: a kind of laser medium temperature equalization reflector, the collar and heat conduction reflecting plate with a locating laser medium, it is characterized in that, the described collar has gap slot, described heat conduction reflecting plate is a vertical plate body that is shaped on the arc groove that sink, be shaped on and the cambered surface boss of laser medium cylinder radius of curvature with arc on the sagging arc groove, described collar gap slot is radially by the laser medium cylinder, be inserted in that to join in the arc groove of described cambered surface boss both sides be an annulus, described laser medium cylinder anchor ear in formed circular hole, and is fixedly connected by the fastener hole screw that the vertical plate body of described sagging arc groove both sides airfoil platform distributes.
The present invention has following beneficial effect than prior art.
The present invention utilizes light emitting diode to need the characteristics of constant temperature work, and adopting radially the cambered surface boss to join in conjunction with collar gap slot is an annulus, forms a temperature equalization reflector.Reflector partly contacts with laser medium, continuous light emitting diode carries out the heat conduction, allow laser medium do not raise by the temperature of light emitting diode direct irradiation part, reduced the temperature thermal gradient that diode single face direct irradiation laser medium portion temperature raises and causes, make that the temperature of the sensitive surface of laser medium and shady face is in a basic balance, thereby improved because the inequality of being heated that diode irradiating laser medium produces causes the deformation of laser medium, improved the stability of the output energy of body laser.Solved laser medium under no liquid cooling situation, the problem of the laser output energy decreases that inequality causes because the laser medium that causes during semi-circular diode side pumped laser medium is heated.
Experiment showed, adopt temperature equalization reflector of the present invention after, the initial value of the output energy of solid state laser is compared with end value and is descended 5%～10% in the identical operating time, and compares output stability in the past and has improved 80%.The present invention can be used for diode side pumped solid state laser structure.
