2.23W diode-pumped Nd:YVO4/LBO Laser at 671nm

A fiber-coupled diode-array-pumped, intracavity frequency doubled by a LBO crystal, high-power Nd:YVO4 red laser at 671nm has been developed in this paper. With incident pump power of 10.6W, employing a type-I critical phase-matched LBO crystal, 2.23W single-transverse-mode red light at 671nm was obtained, with optical-to-optical conversion efficiency up to 21.0%.
