3547-Å pumped parametric oscillation in RD*A

Efficient parametric oscillation in a deuterated rubidium dihydrogen arsenate (RD*A) crystal has been achieved by pumping with the third harmonic of a Nd: YAG laser. A peak power as high as 1.2 MW at 7095 Å and peak powers in excess of 0.5 MW from 6470 to 7850 Å have been obtained.
