A compact multi-kHz UV source tunable from 363nm to 378nm is realized by intracavity SFG in a PPMgSLT OPO. Phase-matched peaks at 334nm and 370nm are observed. A full tuning range of similar to 58nm is predicted. (C) 2007 Optical Society of America

A high-power 532 nm-pumped multikilohertz nanosecond optical parametric oscillator using a periodically poled 1.0 mol. % MgO-doped stoichiometric lithium tantalate crystal that could be operated from room temperature to 200 degrees C without damage is reported. A broad continuous tuning range from 855 to 1410 nM was achieved within a single domain period. Efficient operation of high peak power and watt level average power with a power conversion of 62.5% was measured. These results show that a high-resolution high average power visible tunable source can be realized. (c) 2006 Optical Society of America.
