E-O Crystals ------>> LiTaO3

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 ¦Ìm; E-O Coefficient: r 33 =30.4;
Refractive Indices: n o =2.176, n e =2.180 @ 633 nm.

We can provide the LiTaO3 in a-cut boubles, wafers, slices.
