Abstract

Conversion efficiencies in excess of 50% have been measured in frequency-doubling experiments in KTP using divergent fundamental 1.064-μm beams. Various doubling schemes have been investigated to avoid reconversion effects observed in 9-mm-long crystals. The phase-matching angular acceptance bandwidth, damage-threshold observations, and a measurement of effective susceptibility relative to KD*P are also reported.
