LiIO3 - Lithium Iodate
Introduction
Lithium Iodate (LiIO3) is one of oldest commercial NLO crystals. With high NLO coefficient, LiIO3 is used for frequency-doubling, tripling and mixing of low and medium power lasers. CASTECH provides large size of LiIO3 crystals with high optical homogeneity. They can be as-cut or polished, and sealed housing with AR-coated windows is also available.

Notes
- LiIO3 is highly hygroscopic.
- Please keep it in a dry environment, and sealed housing is recommended.
- CASTECH provides both polishing and sealed housing for LiIO3 crystal.
- LiIO3 is not recommended for high power applications, because of the low damage threshold.
