Abstract

Periodically poled, nearly-stoichiometric lithium tantalate has used to generate visible radiation (by second-harmonic generation using Nd:YAG laser) and mid-infrared radiation (by difference-frequency generation using a Nd:YAG laser and a tunable telecommunications-band laser). Phase-matching conditions have been measured for both interactions at temperatures between 25 degrees Centigrade and 131 degrees centigrade. The absolute conversion efficiency for SHG has been measured and used to derive an effective nonlinear optical coefficient for this process in the periodically poled material. These results can be used to guide the design of laser systems based on nonlinear optical frequency conversion in periodically poled nearly-stoichiometric lithium tantalate.
