Nonlinear Crystals BBO Crystals
BBO Beta-Barium Borate (β-BaB2O4)is a nonlinear optical crystal with combination of number of unique features. It with characters Wide transparency and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity provide attractive possibilities for various nonlinear optical applications.
BBO Crystal optical properties:
Transparency range: 189-3500 nm
Second harmonic generation (SHG) range: 410-2400 nm
Type I phase matching plane: X-Z plane, φ=0°
Type I phase matching plane: X-Z plane, φ=30°
High-Temperature form BBO (BaB2O4) is a negative A-star crystal. It has large birefringence over the broad transparent range from 189 nm to 3500 nm. The physical, chemical, thermal and optical properties of a-BBO crystal are similar to those of b-BBO. However, the nonlinear optical properties of a-BBO crystal is vanished due to the centric symmetry with its crystal structure. It is not recommended using for NLO processes.
