Numerical study of the amplification of the subnanosecond radiation pulses in the gas amplifier of the THL-100 laser system
Possible methods for increasing the energy characteristics of the THL-100 hybrid laser system are investigated by numerical simulation methods. The influence of energy of the input laser radiation and the system of mirrors on the energy and maximum intensity of the laser radiation in the amplifier is investigated. The systems of amplifier mirrors in which the number of passes of the active medium changed from Nm = 27 to 39 are considered. It is shown that at Nm = 27, an increase in the pumping energy of the amplifier from 270 to 400 (J) allows an increase in the output radiation energy by a factor of 2.6 (to 8.34 J) with a maximum radiation intensity in the amplifier of no more than 7 GW cm-2 . Compressing such a beam to an initial duration of 50 fs will allow the average output power of the THL-100 to be increased to 160 TW .
