Self-contained compact pulsed laser based on an auto-wave photon-branched chain reaction

The possible construction of a self-contained and compact pulsed chemical H F-laser based on an auto-wave photon-branched chain reaction initiated in a gaseous disperse medium composed of H-2-F-2-O-2-He and Al particles by foc used external IR radiation is theoretically substantiated. It is shown that an autonomous system and minimization of the parameters of the main pulsed HF-laser units are achievable due to both the effect of ignition of the la ser-chemical reaction in an auto-wave regime under the condition of externa l beam focusing and the effect of a huge laser energy gain of 10(11). These effects provide strong reduction of the input pulse energy necessary for i nitiation up to similar to 10(-8) J, and make it possible to construct a se lf-contained laser with kilojoule output energy, which can be initiated by a small submicrojoule master oscillator powered by an accumulator. Due to a n increase in the general pressure of working gases up to P = 2.3 bar and o ptimization of the parameters of the dispersed component (AI particles with radius r(0) = 0.09 mum and concentration N-0 = 1.4 x 10(9) cm(-3)) and the composition of the working mixture, the HF-laser system will ensure an out put energy up to similar to 1.5 kJ in a pulse from the rather small volume of similar to 2 L of the active medium.
