LiTaO3

Quantity Order:

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 ¼m; E-O Coefficient: r 33 =30.4
Refractive Indices: n o =2.176, n e =2.180 @ 633 nm

DeLn Optics can provide the LiTaO3 wafers and slices.

Wafers :
