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). Main properties include:

• Transparent Range: 0.4 - 5.0 μm; E-O Coefficient: r33=30.4; 

• Refractive Indices: no=2.176, ne=2.180 @ 633 nm.

Maximum LiTaO3 SAW wafer size we can offer is 6 inch in diameter.
