Nd:YVO4 (Neodymium Doped Yttrium Vanadate)
Shown excellent in efficiency, physical, optical and mechanical properties, Nd:YVO4 crystal is widely applied as laser material to diode-pumped solid-state (DPSS) lasers to yield stable and powerful red, green and infrared laser. In comparison with Nd:YAG material for diode-pumping applications, Nd:YVO4 lasers have the following features:
- lower lasing threshold and higher slope effciency;
- large stimulated emission cross-section at lasing wavelength;
- high absorption over a wide pumping wavelength bandwidth;
- low dependency on pumping wavelength and easier to yield single mode output.
We provide customers with different kinds of dopants and different doping levels of Nd:YVO4 crystals on a competitive pricing basis.
