Abstract

A red-wavelength semiconductor disk laser (SDL) optically pumped by gallium nitride laser diodes is reported. This is believed to be the first demonstration of a directly diode-pumped visible wavelength SDL. In this initial demonstration, pump-power-limited continuous-wave output power up to 12.2 mW was achieved around room temperature in a single transverse mode with 2 output coupling. Insertion of an intracavity birefringent filter allowed tuning of the output over 11 nm around a centre wavelength of 672 nm.
