Continuous-wave operation of Nd : YVO4 at 1.06 and 1.34 μ

Abstract
Continuous‐wave plane‐polarized outputs of 1 W at 1.06 μ and 0.35 W at 1.34 μ were obtained by end pumping small samples of Nd : YVO4 with an argon‐ion laser. Slope efficiencies and material losses were determined. At 1.06 and 1.34 μ, Nd : YVO4 lasers can substantially outperform Nd : YAG lasers. Self‐Q‐switched operation of Nd : YVO4 at both wavelengths was obtained by resonator misalignment.
