STABLE, EFFICIENT, OPTICAL PARAMETRIC OSCILLATORS PUMPED WITH DOUBLED Nd: YAG

Singly resonant LiNbO3 oscillators with pump depletion as high as 67% and average visible powers as high as 105 mW are reported. These oscillators are pumped with the doubled frequencies of a repetitively pulsed Nd: YAG laser to produce tunable radiation from 0.55 to 3.65 μm. A bleaching of optically induced index inhomogeneities has been observed when operating at relatively high average powers.
