Tunable visible solid-state lasers based on second-harmonic generation of LiF:F(2) in potassium titanyl phosphate

Opt Lett. 1998 Feb 1;23(3):192-4. doi: 10.1364/ol.23.000192.

Abstract

A new broadly tunable visible solid-state laser is reported. Wavelengths between 550 and 610 nm are generated by intracavity frequency doubling of tuned and free-running room-temperature pulsed LiF:F(2)(-) lasers in potassium titanyl phosphate. Second-harmonic energy of 1.3 mJ has been achieved, corresponding to a fundamental-to-second-harmonic conversion efficiency of 20%. Operation is optimized with respect to LiF:F(2)(-) laser parameters.
