On the possibility of obtaining high energy parameters from an IR-initiated thermal-chain explosion H-2-F-2 laser

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.
