More info

Bismuth Borate (BIBO) Crystal is a high-performance nonlinear optical material, known for its large effective nonlinear optical coefficient, which is 3.5-4 times higher than LBO crystals and 1.5-2 times higher than BBO crystals. It also boasts a high damage threshold and excellent resistance to deliquescence, making it ideal for use in harsh environments. BIBO crystals are highly effective in frequency doubling applications, especially for blue laser generation, offering significant advantages over other nonlinear crystals. Heeger Materials (HM) provides high-quality Bismuth Borate (BIBO) crystals for advanced laser and nonlinear optical applications.
