Paper Abstract

We have developed an accurate simulation program to predict the performance of flashlamp- pumped Titanium Sapphire (TiS) lasers. The program has been benchmarked to several experimental lasers with energy outputs from 0.1 to 1.0 Joules per pulse. The results for lasers operating in both long-pulse and Q-switched modes agree with experimental results to within 20%. We have used this program to explore energy scaling of TiS laser oscillators from 1.0 to 10.0 Joules using realistic values for lamp pulse energy loading and TiS material Figure-of- Merit (FOM). We present here results of this energy scaling as explicit functions of laser rod diameter, length, doping level, Figure of Merit, use of dye converters, pump pulse length and number of lamps. The results indicate that with proper lamp coupling, via reflectors, etc., lasers with pulse energies greater than 10 Joules are possible with electrical-to-output efficiency greater than 1%.
