LiIO3 |
Lithium Iodate (LilO3) crystal, an uniaxial nonlinear crystal with high nonlinear coefficients and wide transparency range, is used to frequency double the low and medium power Ti:Sapphire, Alexandrite, Cr:LiSrAlF6 and Cr:LiCaAlF6 lasers, and also to double and triple of Nd:YAG lasers and auto-correlators for measuring ultra-short pulse width.

Notes
-
LiIO3 is hygroscopic highly,sealed housing is recommended. if possible, please keep it in a dry environment,
-
Due to its low damage threshold. LiIO3 is not recommended for high power applications.
-
Due to its small acceptance angles and large walk-off angle, tight focusing is not recommended
