China Beta-Barium Borate Crystal (β _BaB2O4, BBO)

BBO crystal is an important nonlinear optical crystals with combination of unique optical properties. Broad transmission and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity provide attractive possibilities for various nonlinear optical applications.

China Beta-Barium Borate Advantages:
Broad phase matching (SHG) range from 409.6nm to 3500nm
Wide transmission region from 190nm to 3500nm
Large effective SHG coefficient
High damage threshold of 10 GW/cm2 for 100 PS pulse-widths at 1064nm
High optical homogeneity with Dn 10-6/cm2
Wide temperature bandwidth of about 55° (for type I SHG 1064nm)
Good mechanical and physical properties
Beta-Barium Borate’s Applications
Beta-Barium Borate is of particular importance in the visible and far UV. A wide variety of phase-matching applications are possible.
Frequency-doubling, -tripling and -mixing of dye lasers
Second, third, fourth, and fifth harmonic generation of ND doping lasers
Second harmonic generation to generate wavelengths as short as 204.8nm
Shorter wavelengths(193nm) can be generated by sum frequency mixing
Optical parametric amplifiers (OPA) and optical parametric oscillators (OPO)
Second, third, and fourth harmonic generation of Ti: Sapphire lasers
Frequency-doubling of Argon ion, Cu-vapor and Ruby lasers
