LiNbO3 Crystal

LiNbO3 CrystalLiNbO3(Lithium Niobate) is one of the most attractive materials for optoelectronics. A great variety of devices has been developed based upon this material having unique electro-optical, photoelastic, piezo-electric and non-linear properties combined with good mechanical and chemical stability and wide transparency range.


Bluebean Optical provides high quality, large LiNbO3 crystals for laser frequency doublers, OPOs and quasi-phase-matched doublers, waveguide substrates and SAW wafers.
