LASERS: A pulsed hydrogen fluoride amplifier initiated by vibrational excitation of HF molecules by laser radiation
Abstract
An H2 — F2 amplifier initiated by a resonant vibrational excitation of HF molecules by a pulsed hydrogen fluorine laser is theoretically simulated. Numerical calculations are performed with allowance for an inhomogeneity of the initial HF concentration that appears due to specific features of preparing the experimental laser mixture. The estimated energy output for a mixture of H2 : F2 : O2 : He = 100 : 600 : 30 : 100 Torr is 10 — 20 JL-1 for an average initial HF pressure along the amplifier axis of 0.1 — 0.5 Torr. The laser-radiation energy gain on a length of 4 m is 5 — 10.
