Author Affiliations +
This paper presents a first demonstration of a diode pumped Potassium laser. Two narrowband laser diode arrays with a linewidth about 10 GHz operating at 766.7 nm were used to pump Potassium vapor buffered by Helium gas at 600 torr. A stable laser cavity with longitudinal pumping and orthogonal polarizations of the pump and laser beams was used in this experiment. A slope efficiency about 25% was obtained.
