Neodymium-doped yttrium vanadate (Nd:YVO4). Nd:YVO4 is an excellent crystal for diode-pumped lasers, especially low-to-medium power. Compared with Nd:YAG, Nd:YVO4 offers higher pump absorption and a larger stimulated-emission cross-section. Diode-pumped Nd:YVO4 combined with LBO, BBO, or KTP provides efficient frequency doubling for NIR, green, blue, and UV all-solid-state sources. Nd:YVO4 lasers serve machinery, materials processing, spectroscopy, wafer inspection, displays, medical testing, laser printing, and storage. Nd:YVO4 diode-pumped systems are replacing water-cooled ion and lamp-pumped lasers, especially for compactness and single-longitudinal-mode output.
