Nd YVO4
Nd:YVO4 (neodymium-doped yttrium vanadate) is an excellent laser crystal suitable for laser-diode-pumped lasers, particularly at low and medium powers. Compared with Nd:YAG, Nd:YVO4 has a higher pump-light absorption coefficient and a larger stimulated-emission cross section. Combining diode-pumped Nd:YVO4 with crystals having high nonlinear coefficients, such as LBO, BBO, and KTP, achieves good frequency-doubling conversion efficiency and enables all-solid-state lasers emitting in the near-infrared, green, blue, and ultraviolet ranges. Nd:YVO4 lasers are now widely used in machinery, material processing, spectroscopy, wafer inspection, displays, medical testing, laser printing, and data storage. Nd:YVO4 diode-pumped solid-state lasers are rapidly replacing conventional water-cooled ion lasers and lamp-pumped lasers, particularly for miniaturization and single-longitudinal-mode output.
