Optical Grade LiTaO3(LT) Wafer
LiTaO3 crystal is also widely used E-O crystal, due to its optical, NLO and E-O poperties similar to those of LiNbO3 crystal, but with higher damage threshold (> 500 MW/cm2 for ns pulsed).
Applications
1 ) Quasi-phase Matching for SHG and OPO 2 ) Pyroelectric Infrared Detector
