Neodymium-Doped Yttrium Orthovanadate (Nd:YVO4) Crystal | Laser Crystal Material


Introductions of Nd:YVO4 crystals:

Nd:YVO4 is one of the most efficient solid-state laser host crystal at present. Its large stimulated emission cross-section at laser 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 the high power, stable and cost-effective diode laser-pumped solid-state lasers.
Nd:YVO4 lasers have been used in many areas of military affairs, information industry, etc.


Main physical and optical properties of Nd:YVO4 crystals:

  • Atomic Density: ~1.37 x 1020 atoms / cm3
  • Crystal Structure: Zircon Tetragonal, space group D4h, a=b=7.12, c= 6.29
  • Density: 4.22g / cm3
