Abstract
A method and apparatus for parametric conversion of electromagnetic radiation in KNbO.sub.3 crystals of optical energy at a wavelength near 1 .mu.m to optical energy at wavelengths in the range from 1.4 .mu.m to 4.6 .mu.m. A pump beam and a signal beam impinge on a KNbO.sub.3 crystal and interact to produce optical energy at an idler wavelength and a signal wavelength at the expense of optical energy of the impinging pump beam wavelength. The KNbO.sub.3 crystal has an orientation axis which is aligned with the direction of the impinging pump and signal energy and is on a locus defined by a minimum phase relation between the energy at the pump, signal, and idler frequencies.
