Abstract
The results of experimental study and numerical modeling of the high-power photoinitiated pulsed chemical DF/HF lasers operating in modes of free-running and amplification in the cascade scheme 'master generator (MG)- amplifier (A)' are presented. The comparative analysis of the laser operation efficiency for these modes with the object of obtaining maximal energy characteristics and radiation brightness is carried out. The maximal specific energy of 40 - 50 J/l and the maximal total energy of 2.9 - 3.1 kJ at divergence of 10-3 radian are obtained in free-running mode for DF- and HF-laser and values of 12 J/l and 290 J respectively are obtained at divergence of 8 X 10-5 radian for HF-laser. In mode of MG - A it is obtained in experiment 37 - 42 J/l, 2.9 - 3.4 kJ. On the base of numerical simulation it is possible to make a forecast as 60 J/l, 10 - 20 kJ and 5 X 10-5 radian with efficiency > 50%.
