Vi. Igoshin et al., On the possibility of obtaining high energy parameters from an IR-initiated thermal-chain explosion H-2-F-2 laser, QUANTUM EL, 31(2), 2001, pp. 135-138
A chemical H-2-F-2 laser initiated by IR radiation through vibrational exci
tation of HF molecules is studied theoretically under the conditions of a b
ranched thermal-chain reaction caused by the thermal dissociation of gaseou
s additions to the laser mixture. It is demonstrated that, using the F2SO3
addition at a partial pressure of 40 Torr, the H-2-F-2 laser with a mixture
pressure of 1 bar, initiated by a pulse of a hydrogen fluorine laser can p
rovide the output exceeding 200 J litre(-1) in 20-ns laser pulses.
