SAW Grade LiNbO3 Single Crystal For Acousto-optic Devices


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.


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.

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 provides:

  • LiNbO3 wedges used for fiber optical isolators and circulators.
  • Reliable delivery
  • Strict quality control
  • Technical support
  • Very competitive prices

LiNbO3 Crystal Applications:

1. Pockels Cells
2. Q-switches
3. Phase modulators
4. Surface acoustic wave(SAW) wafers
