Temperature tunable infrared optical parametric generation based on periodically poled MgO:LiNbO crystals

Abstract

By using a short-pulse field, periodically poled grating (? = 29 ?m) was successfully fabricated in a 1.0 mm-thick MgO:LiNbO₃ (mole fraction of doped MgO is 5%). A high-repetition-rate optical parametric generation (OPG) based on periodically poled MgO:LiNbO₃ (PPMgLN) was pumped by a 1.064 ?m acousto-optically Q-switched Nd:YVO₄ laser. With 3 W of input pump power, 44 mW of output signal power was obtained at a conversion efficiency of 1.5%. Tunable infrared (IR) output from 1.4538–1.4750 ?m was also obtained by tuning the temperature of PPMgLN, which is 45°C–160°C.
