±-BBO (±-BaB2O4) is a negative uniaxial crystal which has large birefringence over a broad transparent range of 190nm to 3500nm. ±-BBO is an excellent crystal especially in UV and high power applications. The physical, chemical, thermal, and optical properties of alpha-BBO crystal are similar to those of Beta-BBO. However, there is no second order nonlinear effect in alpha-BBO crystal due to the centrosymmetry in its crystal structure and thus it has no use for second order nonlinear optical processes. Instead, alpha BBO is widely used for fabrication of polarizers, polarizing beam displacers, phase retarders, birefringent plates, and time delay compensators especially those for UV and high power lasers. Applications of ±-BBO Crystals High power Beam displacers for isolators. High power Polarizer Time delay compensators Advantages of ±-BBO Crystals High UV transmittance Large birefringence High damage threshold Here at OST Photonics, we value integrity, accountability, and punctuality. Our vision is to be the most professional and reliable supplier of crystal products in the world.
