Parametric oscillation at 3.2 mu m in KTP pumped at 1.064 mu m

The author reports the stable generation of 0.2-W average power IR pulses around 3.2 mu m from the KTP parametric oscillator pumped by the Nd:YAG laser at 1.064 mu m. In addition, improved Sellmeier's equations, which correctly predict almost all of the nonlinear experiments thus far reported, are presented, together with the absolute values of d/sub 31/ and d/sub 32/.<
