Frequency-Doubled Neodymium-Yag Pumped Dye Study.

Abstract

The goal of this program was to obtain 125 mJ (minimum) pulses in the .53 to .70 micrometer region of the spectrum. It was originally envisioned by the AFWL in their RFP that this goal would be accomplished by frequency doubling the 1.32 micrometer output from a pulsed Nd:YAG laser system. However, such an approach is difficult for at least two reasons. First, competition from the 1.06 micrometer transition in Nd:YAG makes it difficult to obtain the required 1.32 micrometer pulse energies in a low-order transverse mode. Secondly, a damage resistant, 90 degree phase-matchable nonlinear crystal for doubling 1.32 micrometer is not readily available. Thus the approach which was recommended in our proposal and which was followed on this program was to (1) generate 1.06 micrometer pulses with a Nd:YAG oscillator/amplifier chain, (2) generate second-harmonic pulses at .53 micrometer using deuterated cesium dihydrogen arsenate as the nonlinear material, and (3) use the 0.53 micrometer pulses to pump a dye laser.
