United photonics technologyBBO Crystal (Beta-Barium Borate Crystal)

BBO crystal is an important nonlinear optical crystal 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.

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

BBO's main applications:

*Second, third, fourth and fifth harmonic generation of Nd lasers

*Frequency-doubling, -tripling and -mixing of Dye lasers

*Second, third and fourth harmonic generation of Ti:Al O and Alexandrite lasers

*Optical parametric amplifiers (OPA) and optical parametric oscillators (OPO)

*Frequency-doubling of Argon ion, Cu-vapor and Ruby lasers
