- W2006845250 abstract "The possible construction of a self-contained and compact pulsed chemical HF-laser based on an auto-wave photon-branched chain reaction initiated in a gaseous disperse medium composed of H<sub>2</sub>-F<sub>2</sub>-O<sub>2</sub>-He and Al particles by focused external IR radiation is studied theoretically. It is shown that minimization of the parameters of the main pulsed HF-laser units are achievable due to both the effect of ignition of the laser-chemical reaction in an auto-wave regime under the condition of external beam focusing and the effect of a huge laser energy gain of 10<sup>11</sup>. These effects provide strong reduction of the input pulse energy necessary for initiation, down to ~10<sup>-8</sup> J, and make it possible to construct a self-contained laser with kilojoule output energy per pulse, which can be initiated by a small sub-microjoule master oscillator powered by an accumulator. Due to an increase in the general pressure of the working gases, up to P = 2.3 bar, and optimization of the parameters of the dispersed component (Al particles with a radius of r<sub>0</sub> = 0.09 μm and a concentration of N<sub>0</sub> = 1.4×10<sup>9</sup> cm<sup>-3</sup>), and the composition of the working mixture, the HF-laser system will ensure an output energy up to ~ 1.5 kJ in a pulse, produced in a small volume of ~ 2 L of active medium." @default.
