Second Harmonic Generation

Abstract

The investigations under the subject contract had the objectives of producing high average powers in a Second Harmonic Generation laser system at a wavelength of 0.532 microns with a short pulse and high repetition frequency format. The program's objectives were to be achieved by using a high average power CW Nd:YAG laser combined with electro-optical Q-switching techniques and mode-locked pulse injection as a source of 1.065 micron power drive to a nonlinear crystal. Both well known and new materials were investigated in order to achieve high conversion efficiencies. Damage and the thermal failure of materials was an area of special concern in this program.
