Abstract

The design and experimental testing of an Optical Parametric Oscillator generating 2 Watts of continuous wave radiation at 3.5 micron is presented. The oscillator uses a KTA (Potassium Titanyl Arsenate) crystal as the nonlinear medium, pumped by the 1.06 mm intracavity radiation of an Optically Pumped Semiconductor Laser (OPSL). A review of the nonlinear characteristics of KTA is presented, and design criteria for the OPSL intra-cavity pumped OPO are given. The experimental results are presented and discussed.
