BiB3O6 (BIBO) is a newly developed nonlinear optical crystal. It possesses large effective nonlinear coefficient, high damage threshold and inertness with respect to moisture. Its nonlinear coefficient is 3.5 - 4 times higher than that of LBO, 1.5 -2 times higher than that of BBO. It is a promising doubling crystal to produce blue laser.
Chemical and Structural Properties
Crystal Structure | Monoclinic，Point group 2 |
Lattice Parameter | a=7.116Å, b=4.993Å , c=6.508Å , β=105.62°, Z=2 |
Melting Point | 726℃ |
Mohs Hardness | 5-5.5 |
Density | 5.033 g/cm3 |
Thermal Expansion Coefficient | αa=4.8 x 10-5/K , αb= 4.4 x 10-6/K, αc=-2.69 x 10-5/K |
Within the domain of nonlinear crystals, Bismuth Triborate (BIBO crystal) stands as a comparatively novel material when compared with counterparts like Beta Barium Borate (BBO) and Lithium Triborate (LBO). Notably, BIBO surpasses BBO in terms of its heightened effective nonlinearity, while also offering a broader bandgap in comparison to Potassium Titanium Oxide Phosphate (KTP). This combination renders BIBO crystal exceptionally suited for harnessing the phenomenon of second harmonic generation (SHG) within solid-state lasers and laser diodes. And is particularly advantageous for generating wavelengths in the green and blue spectrum through continuous-wave (CW) radiation. The elevated effective nonlinearity of BIBO crystal not only enhances the efficiency of the SHG process but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser systems.
