Phase-matching properties of KNbO3 in the mid-infrared.
KNbO(3) has been found to be phase matchable for type 1 second-harmonic generation up to 2.4 microm at 22 degrees 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 CO(2) laser harmonics between 3.5303 and 5.2955 microm are presented.
