Stimulated light scattering in inverted carbon dioxide induced by a thermal nonlinearity

Soviet Journal of Quantum Electronics (1983)

Igor' M Bel'dyugin Л А Васильев М Г Галушкин Aleksandr M Seregin N V Cheburkin

A theoretical analysis is made of some features of stimulated light scattering which may occur as a result of the dependence of the rate of heat release on the radiation intensity in the active medium of a CO2 laser. The main energy and spectral characteristics of this process are found. It is shown that the parameters of the scattered radiation depend strongly on the time lag of the heat release which is governed by the relationship between the modulation period of the radiation intensity and the characteristic time of the radiation-induced heating of the medium.

Emission characteristics of a pulsed CO₂laser with a self-filtering unstable resonator under conditions of a strong self-interaction of radiation in the active medium. II. Results of experiments and optimization of the output characteristics

Soviet Journal of Quantum Electronics (1991)

S. V. Bardakovskii N A Blinov Yu P Gorbachev V M Tsygankov V. N. Koterov

Theoretical and experimental investigations were made of the dynamics of an atmospheric-pressure pulsed CO2 laser with a self-filtering unstable resonator pumped by pulses of ~ 40 μs duration. The resonator ensured that the divergence of the output radiation was close to the diffraction limit even when the active medium was so inhomogeneous that the output intensity suffered 100% modulation. The results demonstrated that the output characteristics could be improved by optimization of the resonator parameters.

Investigation of the energy and spectral characteristics of a cw industrial electron-beam-controlled laser using isotopically modified carbon dioxide

Soviet Journal of Quantum Electronics (1986)

Experimental and theoretical investigations were made of the operation of a cw continuous-flow electron-beam-controlled laser using a binary mixture of naturally occurring and isotopically modified carbon dioxide molecules. The replacement of 12C16O2 with 13C16O2 made it possible to alter the emission frequency without a significant loss in the output power and laser efficiency.
