Nd:YVO4 - Neodymium Doped Yttrium Orthvanadate

Nd:YVO4 is one of the most efficient laser host crystal currently existing for diode-pumped solid-state lasers. Its large stimulated emission cross-section at lasing wavelength, high absorption coefficient and wide absorption bandwidth at pump wavelength, high laser induced damage threshold as well as good physical, optical and mechanical properties make Nd:YVO4 an excellent crystal for high power, stable and cost-effective DPSS laser. Developments have shown that Nd:YVO4 can produce powerful and stable IR, green, blue lasers with the design of Nd:YVO4 and frequency doubling crystals.

Compared with Nd:YAG and Nd:YLF for diode laser pumping, Nd:YVO4 lasers posses the advantages of lower dependency on pump wavelength and temperture control of a diode laser, wide absorption band, higher slope efficiency, lower lasing threshold, linearly polarized emision and single-mode output. For the applications in which more compact design and the single frequency output are desired, Nd:YVO4 shows its particular advantages over other commonly used laser crystals. The diode-pumped Nd:YVO4 compact laser and its frequency-doubled green, red or blue laser light will be the ideal laser tools of mechining, material processing, spectroscopy, wafer inspection, light show, medical diagnostics, laser printing and the most widespread applications.
