Abstract

The invention comprises a generator of an excited state of a gas molecule, particularly of the oxygen singlet-delta O2(1Δ), which is produced directy from the molecular ground-state (O¿2?) by means of a cold plasma electrical excitation method. The inventive method for plasma and/or excited molecular state generation comprises the steps of (a) providing a gas (e.g. O2); (b) applying a ultra-high voltage pulse above ionization breakdown (with high values of the electric field normalized to plasma density, E/N ≥ 180 Td) thereby forming a plasma; (c) applying additional ultra-short (τ ≃5-15 ns) pulses at a repetition rate (20-40 KHz) sufficient to sustain quasi-continuous ionization of the plasma, while (d) causing a current to flow to the plasma by applying the required pump value of E/N lower than the glow potential of the plasma (E/N ≃ 10 Td). The invention comprises as well an inventive pulse circuit for generating the required pulses. Preferred configurations comprise an integral generator (850) with a heat exchanger (880). A primary object of the invention is to enable an electrical oxygen-iodine laser (800) activated by a power supply system (840), whereby the required oxygen singlet-delta O2(?1¿Δ) is produced electrically by the inventive generator (840,850,880) rather than chemically as in conventional chemical oxygen-iodine lasers.
