Optical Grade Fe doped LT Fe:LiTaO3 Wafers Lithium Tantanlate Wafer
LiTaO3 is an E-O crystal widesly used for E-O devices, due to its good optical NLO and E-O properties, as well as high damage threshold. Crystro supplies hign quality LiTaO3 boules and wafers with the following specifications for standard applications. We can also offer other specification upon request:
Crystro's Fe:LiTaO3 is grown by Czochralski method.Max diameter reach 6inch,can offer kinds of size per required.
Anhui Crystro participate in the kinds exhibitions every year: Laser World of Photonics Munich, Shanghai, Photonics West in San Francisco, CIOE in Shenzhen, etc.We looking forward to meet you.
