CASTECH--BBO Crystals
Description
Beta-Barium Borate (β-BaB2O4 or BBO), discovered and developed by FIRSM, CAS (Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences), now is manufactured and marketed by CASTECH Inc. The high-quality crystal boule is steadily available from CASTECH, who holds specialized proprietary techniques (flux-method) of the BBO crystal growth.

Frequently Asked Questions
BBO crystal is a beta-barium borate crystal discovered and developed by FIRSM, CAS, now manufactured and marketed by CASTECH Inc.
BBO crystal has a broad phase matchable range, wide transmission region, large effective second-harmonic-generation coefficient, high damage threshold, high optical homogeneity, and wide temperature-bandwidth.
BBO crystal can be used for second, third, fourth, and fifth harmonic generation of Nd:YAG lasers, intracavity SHG of high power Nd:YAG lasers, frequency-doubling and tripling of ultrafast pulse lasers, and OPO and OPA for generating a widely tunable coherent radiation from UV to IR.
CASTECH provides DualBandAR-coating, BroadBandAR-coating, BroadBandP-coating, and other coatings upon request for BBO crystal.
The quality warranty period for BBO crystal is one year under proper use.
