Neodymium Doped Yttrium Orthvanadate (Nd:YVO4)

Nd:YVO4 is one of the most efficient laser host crystal currently existing for diode laser-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 diode pumped solid-state lasers. Recent developments have shown that Nd:YVO4 can produce powerful and stable IR, green, bule 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 possess the advantages of lower dependency on pump wavelength and temperature control of a diode laser, wide absorption band, higher slope efficiency, lower lasing threshold, linearly polarized emission and single-mode output. For the applications in which more compact design and the single-longitudinal-mode output are needed, Nd:YVO4 shows its particular advantages over other commonly used laser crystals. The diode laser-pumped Nd:YVO4 compact laser and its frequency-doubled green, red or bule laser will be the ideal laser tools of machining, material processing, spectroscopy, wafer inspection, light show, medical diagnostics, laser printing and the most widespread applications.

With advanced technology on growing high optical quality and large size Nd:YVO4 crystals, Dream Lasers steadily provides as large as 35x50mm3 Nd:YVO4 bulk crystal and 20x20mm3 finished crystal with very low intrinsic optical loss. Now, Dream Lasers massively produces and provides high quality Nd:YVO4 crystals at very competitive prices.
