Core Optronics Co.,Ltd is a professional manufacturer with high quality of BBO crystal. We can offer various size and specifications of BBO crystals according to customers' requests.

Description:

Beta-Barium Borate (B-BaB2O4, BBO), is a nonlinear optical crystal with combination of number of unique features.

Features: 

• Broad phase matchable range from 410 nm to 3500 nm;   

• Wide transmission region from 190 nm to 3500 nm; 

• Large effective second-harmonic-generation (SHG) coefficient about 6 times greater than that of KDP crystal;

• High damage threshold of 10 GW/cm2 for 100ps pulse-width at 1064nm; 

• High optical homogeneity with dn ~10-6/cm;

• Wide temperature-bandwidth of about 55 C 

Applications: 

• Second, third, fourth and fifth harmonic generation of Nd doping lasers;

• Second harmonic generation to generate wavelengths as short as 204.8 nm;

• Shorter wavelengths (193nm) can be generated by sum frequency mixing;

• Frequency doubling, tripling and -mixing of Dye lasers;

• Second, third and fourth harmonic generation of Ti:Sapphire lasers;

• Optical parametric amplifier (OPA) and optical parametric oscillators (OPO);

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

• Transverse field Pockel cells made from BBO useful when high average powers or short wavelengths used.
