Abstract.

A compact and efficient diode-pumped intracavity-frequency-doubled Nd:GdVO4/KTP green laser is demonstrated with a flat–flat cavity design. With a 1.3 at. % Nd3+-doped GdVO4 crystal and pumped at the weak-absorption peak of 806 nm, the second-harmonic output power at 532 nm was measured to be 1.95 W at an incident pump power of 8.4 W, corresponding to an optical conversion efficiency of 23.2%. The output characteristic at the fundamental wavelength of 1.063 μm was investigated with two different pump wavelengths. More than 4.5-W output power was generated when the laser was pumped at 806.2 nm.
