Most efficient laser host crystal Nd:YVO4 

 

 

Description
Yttrium Vanadate (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.

Nd:YAG crystals Nd:YAG crystal
Nd:YAG crystal
Nd:YAG (neodymium-doped yttrium aluminium garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, typically replaces yttrium in the crystal structure of the yttrium aluminium garnet (YAG), since they are of similar size. Generally the crystalline host is doped with around 1% neodymium by atomic percent. Applications: Nd:YAG absorbs mostly in the bands between 730–760 nm and 790–820 nm.At low current densities krypton flashlamps have higher output in those bands than do the more common xenon lamps, which produce more light at around 900 nm. The former are therefore more efficient for pumping Nd:YAG lasers.
