NLO Lithium niobate Nolinear Optical Crystal Used In Optical Communication

LiNbO3 (Lithium Niobate) crystal is widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064 nm. Due to its large electro-optic and acousto-optic coefficients.

Both pure LN and MgO doped LN (MgO:LN) crystals with gold coatings on side faces for electrodes are available

MgO doped LiNbO3 (MgO:LN) has similar linear optical properties to pure LiNbO3, but the photorefractive damage threshold is much higher.

Crystro's LiNbO3 crystal is grown by Czochralski method.Max diameter reach 4inch,it's now the biggest size in this filed,we can custom size and specs ,rougness<0.5nm.Magneto-optical single crystals like GGG,SGGG,TGG,TSAG are our main products.

Crystro provides:

LiNbO_{3 wedges used for fiber optical isolators and circulators.}
Reliable delivery
Strict quality control
Technical support
Very competitive prices
