Abstract

KNbO₃ has been found to be phase matchable for type 1 second-harmonic generation up to 2.4 µm at 22 °C. The improved Sellmeier equations that correctly reproduce the nonlinear experiments thus far reported in the literature and our new experimental results for harmonic generation of CO₂ laser harmonics between 3.5303 and 5.2955 µm are presented.
