V YAG Q Switch Crystals

V: YAG is a new type of crystal material for passive q lasers. It can be applied in the range of 1064-1440 nm wavelength. V: YAG has been used in various active media, because this material has high damage threshold, high contrast of Q-switch, excellent mechanical and thermal properties. It generally can be grown by Czochralski method.
