Abstract
The mathematical model of the XeF(C–A) amplifier of hybrid laser system THL-100 was developed. The numerical investigations of spatial distribution of small-signal gain coefficient in active medium were carried out. The effect of the mirrors reflection coefficient, pumping power, and input pulse energy on the output energy was investigated. It is shown that at input pulse energy of 20 mJ and a mirror reflection coefficient of 0.995 it is possible to increase the output energy up to 3.5 J.
