Paper Abstract

Design and performance details of a high energy diode pumped slab amplifier (HEDPSA) system are given. The output from a 200 millijoule commercial Gaussian coupled Nd:YAG laser is amplified to 1 Joule per pulse with good beam quality at a repetition rate of 20 Hz. The system comprises two zigzag geometry Nd:YAG slab amplifier stages pumped by 2D semiconductor laser diode arrays. Details of the amplifier optical design are given, highlighting the techniques used for compensation of thermal distortions in the laser slabs. Thermal lensing results show good agreement with thermal and optical models of the system. Good agrement is also shown with theoretical models of amplifier performance.
