Product description
Lithium iodate crystal (LiIO₃) is a nonlinear crystal that has been used in industry relatively early. This crystal has a high nonlinear coefficient and can be used for second and third harmonic generation and frequency mixing of medium and low-power lasers. Zhongce Technology provides large-sized LiIO₃ crystals with excellent optical homogeneity, and also offers polishing, coating services and sealed brackets for LiIO₃ crystals.

Remarks:
- LiIO₃ crystals are prone to deliquescence, and it is recommended to store them in a dry and sealed environment.
- Zhongce Company can provide polishing and bracket assembly services.
- LiIO₃ crystals have a relatively low damage threshold and are not recommended for use in high-power lasers.
