Barium borate (BBO) is a nonhydroscopic and chemically stable material. Crystallization takes place in two phases, alpha and beta, and the phase transition temperature equals to 925±5°C. The higher temperature phase-alpha is centric symmetrical within its crystal structure, whose square nonlinearity tensor components are identically equal to zero. In contrast to the alpha-phase, the Beta-phase of BBO is non-centric symmetrical and the crystals grown in this phase possess nonlinear optical properties.
Beta-BBO was discovered and developed in 1984 by a group of Chinese investigators at Fujian Institute of Research on the Structure of Matter, Chinese Academy of Science. It is a crystal frequently used for frequency mixing and other nonlinear optics applications.
Beta Barium Borate Features:
Wide transmission region from 190 nm to 3500 nm
Broad phase-matchable range from 409.6 nm to 3500 nm
Large effective second-harmonic-generation (SHG) coefficient
High damage threshold
High Optical homogeneity
Excellent mechanical and physical properties
Beta Barium Borate Applications:
Second, third, fourth and fifth harmonic generation of Nd:YAG and Nd:YLF lasers
Frequency-doubling, -tripling and -mixing of Dye lasers
Second, third and fourth harmonic generation of Ti:Sapphire and Alexandrite lasers
Optical parametric amplifier (OPA) and optical parametric oscillators (OPO)
Frequency-doubling of Argon ion, Cu-vapor and Ruby lasers.
BBO crystal or Beta-Barium Borate (β-BaB2O4), has large effective second harmonic generation (SHG) coefficient about 6 times greater than that of KDP crystal, as well as excellent electro-optic crystal applied in the application of high power laser system at working wavelength from 200nm to 2500nm, such as a Q-switching CW diode pumped Nd:YAG laser and so on.
