Description:
Bismuth Borate (BiBO, BiB3O6) is a highly efficient nonlinear optical crystal, renowned for its substantial nonlinear optical coefficients, which are 3.5 to 4 times higher than those of LBO and 1.5 to 2 times higher than those of BBO. BiBO crystals exhibit excellent damage thresholds and low deliquescence, making them ideal for high-efficiency blue light generation. These properties make BiBO crystals highly suitable for a variety of nonlinear optical processes, including Optical Parametric Oscillators (OPO) and Difference Frequency Generation (DFG).
