BBO Crystals
 is a nonlinear optical crystal which combines a number of unique features. These features include wide transparency and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity. Therefore, BBO provides an attractive solution for various nonlinear optical applications.

BBO crystals is also an excellent electro-optic crystal for high power applications at the wavelength range from 200nm to 2500nm. It can be used for Q-Switching in a CW diode pumped Nd:YAG laser with average power>50W.

High Temperature form BBO ( a -BaB 2 O 4 ) is a negative uniaxial crystal. It has large birefringence over the broad transparent range from 189 nm to 3500 nm. The physical, chemical, thermal and optical properties of a-BBO crystals are similar to those of b-BBO. However, the nonlinear optical properties of a-BBO crystal is vanished due to the centric symmetry with its crystal structure. It is not recommended to use for NLO processes.

What is BBO crystal?

BBO Crystals (beta-BaB2O4) is an excellent non-linear crystal for frequency-doubling (SHG) of Visible and Near IR laser light, OPO/OPG/OPA pumped by ultrafast pulses of wavelengths in the Near IR to UV, and sum-frequency mixing (SFM) into the Visible to the deep UV. Astar BBO Crystal is one of the few practical crystals for use below 500 nm in SHG and SFM.

BBO crystal has broad tunability, high damage threshold, and high efficiency. BBO’s small acceptance angle requires a very good beam quality and its large walk-off results in output beams that are very elliptical or slit-like. Type I is usually much more efficient than the type II operation. BBO can not be used for NCPM (temperature tuned) applications.

BBO is very good for tunable laser sources, such as ultrafast Ti: Sapphire or dye lasers. And it is also widely used for SHG, 3HG, 4HG, and autocorrelation of femtosecond and picosecond Ti:Sapphire lasers; SHG, 3HG, 4HG, 5HG of YAG lasers at 1064 nm and 1320 nm to yield output of 212-660nm; SHG of tunable dye or solid-state laser sources from 410-750 nm to yield output of 205-375 nm, SFM of dye laser and YAG harmonics to yield output of 189-400 nm; DFM (difference-frequency mixing) from the Visible to the IR range up to over 3000 nm; OPO pumped with SHG or 3HG of YAG or Ti:Sapphire with an output range of 400-3000 ; Intracavity SHG of Argon ion lasers (488, 514 nm) or Copper vapor lasers (510 nm, 578 nm).
