Paper Abstract

An engineering approach for the development of laser hardware that takes advantage of the special properties of phase conjugation is reported. The principal advantages of conjugate solid-state lasers are alignment stability and passive compensation of thermal distortion in a double pass laser amplifier chain. Attention is given to the application of phase conjugation techniques to the design, fabrication, and field testing of an Nd:YAG second harmonic 0.5 Joule, 30 Hertz flashlamp pumped laser in a master oscillator power amplifier configuration. The double pass amplifier featured a phase conjugate mirror and a second harmonic crystal within the amplifier chain. The basic Nd:YAG laser produced a doubling efficiency of 75 percent from 1064 to 532 nm. This output was subsequently used as the source, and a conversion efficiency of 80 percent into six wavelengths in the visible spectrum was obtained using stimulated rotational Raman scattering.
