Abstract:

The results of a twelve month program to improve the efficiency of optical pumps for NdYAG lasers are presented. The first task was the development of a flash lamp for pumping Q-switched NdYAG lasers at 10 joules per pulse with pulse repetition rates up to 10 pulses per second, and an overall efficiency of 2. This goal was achieved through improving both the lamp and the circuit. Substantial efficiency improvements were achieved by simmer-pulse operation. A pseudo-simmer circuit was developed that achieves good efficiency and uses only lightweight components. The second task was the development of a lamp for pumping CW NdYAG laser with 5 overall efficiency at 1kW input. Author
