Abstract

A comparative study of Nd:GdVO₄ and Nd:YVO₄ crystal lasers pumped by a cw diode laser has been conducted at the fundamental wavelengths of 1.06 μm and 1.34 μm, as well as when intracavity frequency-doubled to 532 nm and 670 nm, respectively. At these four wavelengths, maximum output powers from the Nd:GdVO₄ crystal laser were 1.27 W, 800 mW, 610 mW, and 82 mW at a diode-launched pump power of 2.9 W. The threshold pump powers were 64 mW, 159 mW, 5 mW, and 12 mW, respectively. All the results obtained from Nd:GdVO₄ were superior to those of Nd:YVO₄, indicating that Nd:GdVO₄ is a more efficient laser crystal than Nd:YVO₄ for diode-pumped solid-state lasers.
