Abstract

A compact tunable UV laser source based on intracavity sum frequency generation in a MgO-doped periodically-poled stoichiometric lithium tantalate optical parametric oscillator is reported. UV output at an 1 mW level of power over the range of 364 to 378 nm with a bandwidth of 0.5 nm was obtained with a crystal that has just one periodically-poled grating period. The full tuning range can be as much as 68 nm , from 324 to 392 nm by varying the crystal temperature from room temperature to 250 ° C . This will cover nearly the entire UVA range.
