Abstract

We report a single-longitudinal-mode continuous-wave Ti : sapphire ring laser that is intracavity frequency doubled in periodically poled lithium niobate (PPLN). Using a multi-grating PPLN crystal, the second harmonic is tunable from 386 to 403 nm – close to the PPLN ultraviolet absorption edge – with a maximum generated power of 114 mW. The wavelength dependence of the critical operating temperature required to eliminate photorefractive effects in the PPLN crystal is determined.
