Abstract

The first demonstration of mid-infrared generation in KNbO₃ by frequency downconversion from a 1.064-micron laser is reported. A 35 percent photon conversion efficiency is achieved for generation of light at 3.4 microns. The phase-matching curve and temperature sensitivity for the process is presented, and the temperature acceptance is measured to be greater than 6.7 cm-°C.
