6inch Diameter LiNbO3 E-O NLO Crsytal Wafer

LiNbO3 is a nonlinear optical grade crystal, it widely used in parametric oscillators, frequency doubling, acousto-optic devices, optical modulators. MgO-doped LiNbO3 can effectively increase the damage threshold of the LiNbO3 crystal..

MgO:LiNbO3 (Magnesium Oxide Doped Lithium Niobate) crystal has similar effective nonlinear coefficients to pure LiNbO3 and exhibits higher optical damage threshold.

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 6inch,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
