SAW Grade Fe doped LT crystal Fe:LiTaO3 Lithium Tantanlate Wafer
Lithium tantalate (LiTaO3), has properties which make it useful for
SAW (surface acoustic wave) devices and, to a different
specification, for optical use. Wafers can be produced with varying
properties, such as "black" wafers free of pyroelectric discharge,
4" (100mm), orientation 36°, 39°, 42 °, 46°, 48°, X-CUT detailed
specifications, or with higher physical strength to withstand
processing during manufacture, resulting in higher yields.
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.
