Description/Abstract

We report on first-order quasi-phase-matched frequency doubling of picosecond pulses to the green, using a sample of periodically poled lithium niobate. In cw mode-locked operation. 330 mW of average green power was generated with an average conversion efficiency of ~52%. With a quasi-cw mode-locked pulse train an average conversion efficiency of ~65% was achieved, and 1.3 W of green power (average power within the 10-ps pulse envelope) was produced. At these powers there was no significant photorefractive damage, as confirmed by measured M^2 beam-quality factors of ~1.1 for both output fundamental and second-harmonic beams.
