OEM Supply Cr:Yag - BBO Crystal – WISOPTIC
OEM Supply Cr:Yag - BBO Crystal – WISOPTIC Detail:
BBO (ẞ-BaB2O4) is an excellent nonlinear crystal with combination of a number of unique features: wide transparency region, broad phase-matching range, large nonlinear coefficient, high damage threshold, and excellent optical homogeneity. Therefore, BBO provides an attractive solution for various nonlinear optical applications such as OPA, OPCPA, OPO etc.
BBO also has advantages of large thermal acceptance bandwidth, high damage threshold and small absorption, thus is very suitable for frequency conversion of high peak or average power laser radiation, e.g. harmonic generation of Nd:YAG, Ti:Sapphire and Alexandrite laser radiation. BBO is the best NLO crystal for the fifth harmonic generation of Nd:YAG laser at 213 nm. Good laser beam quality (small divergence, good mode condition, etc.) is the key for BBO to obtain high conversion efficiency.
In addition, large spectral transmission range as well as phase matching, especially in UV range, makes BBO perfectly suitable for frequency doubling of the Dye, Argon ion and Copper vapour laser radiation. Both Type 1 (oo-e) and Type 2 (eo-e) phase-matching angles can be obtained, increasing the number of advantages for different applications of BBO.
