Abstract : Laser performance in double pulse mode of pumping was studied. The xenon flash lamp was energized by two condenser banks discharged in sequence with a time delay between both discharges. Theoretical analysis of discharge characteristics and of experimental data including discharge current, pumping light and laser output at threshold, and higher energy levels in relation to varying time delay are presented. Improvements in overall laser efficiency as much as 12 per cent in double pulse pumping were obtained as compared with conventional single pulse pumping in the experimental setup. The possibility of adjusting the dynamic impedance of the light source and of modifying pumping light pulse for improvement of laser performance is cited. (Author)
