Diode-pumped Nd:YVO_4 laser with discrete multi-wavelength tunability and high efficiency

Abstract

Selectable and discretely tunable multi-wavelength diode-pumped Nd:YVO4 laser operating at 1064.0, 1073.1, and 1085.2 nm was demonstrated using a single intracavity birefringent plate. Under 11.2 W of absorbed pump power, the maximum output power of more than 3.8 W for any of the three wavelengths was achieved with slope and optical-to-optical efficiencies of more than 45% and 35%, respectively.
