Nd:YVO4 Crystals

Nd:YVO4 crystals is one of the most efficient solid-state laser host crystal today. Its large stimulated emission at aser 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 crystals an excellent crystal for the high power, stable and cost-effective diode laser-pumped solid-state lasers.
