Polarizer NLO Crystals Waveplate High Power Polarization Beamsplitter EO Q-Switch

LiNbO3 crystal

LiNbO3          Lithium Niobate Crystal
Lithium Niobate (LiNbO3) is widely used as electro-optic modulator and Q-switch for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well as modulator for fiber optics, etc. The transverse modulation is mostly employed for LiNbO3 crystal. Also LiNbO3 Crystal is widely used as frequency doublers for wavelength >1um and optical parametric oscillators (OPO) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices.
