BBO

α-BBO (alpha-barium borate) is a nonlinear optical crystal that is formed when low temperature phase beta-barium borate is heated to 925 °C. The position of the barium ions is shifted at this temperature. While both phases have excellent birefringence properties and similar physical, thermal, and optical properties, the α phase has centric symmetry and does not have the second order qualities


α-barium borate is a negative uniaxial crystal with birefringence properties of a wide range of 189nm-3500nm. It is often use for polarizer fabrication, phase retarders, birefringent plates. Time delay compensators, polarizing beam displacers and spontaneous parametric down-conversion.

       High temperature phase of BaB2O4 is an excellent birefringent crystal;           it is characterized by large birefringent coefficient and wide transmission         window from 189nm to 3500nm, particularly it is suitable to make the 

       high power UV polarizer, due to its unique UV transparency and good 

       mechanical properties.


       The physical, chemical, thermal and optical properties of a-BBO crystals         are similar to those of b -BBO, for instance high optical homogeneity 

      (better than 1x10-6/cm), extremely low absorption in the UV to IR range         (<0.5% from 300-2300nm), low hygroscopic susceptibility and high 

       damage threshold
