Optical Pumps for Lasers.
Abstract
The results of a twelve month program to improve the efficiency of optical pumps for Nd:YAG lasers are presented. The first task was the development of a flash lamp for pumping Q-switched Nd:YAG 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 Nd:YAG laser with 5% overall efficiency at 1kW input. (Author)
