CY0495 Beta-barium Borate (BBO)

Beta-barium borate (BBO) is a very important nonlinear crystal because of the broad phase-matching range and useful optical transmission. It has high damage threshold, wide temperature-bandwidth and low thermo-optic coefficient. BBO can be widely used in medical, military and meteorology fields.
