Paper Abstract

A new scheme of direct optical pumping of 4-μm HBr-laser was proposed being based on rather precise coincidence revealed of the principal 2P9 line of DF-laser with R2 line of the fundamental absorption band of molecular gas considered. Lasing at the use of off-axis pumping geometry (pump radiation flounce of 0.2 J/cm2, duration ~300 ns) was observed within (0.4- 15) torr of HBr pressure range. The complex behavior of HBr-laser pulse intensity, duration and time delay on the gas pressure was analyzed. Energy conversion efficiency of ~2% was achieved at P~10 torr. It is believed that the one may be substantially increased by both the optimization of HBr-laser cavity losses and the use of the collinear pump geometry with improved mode-matching.
