BBO (beta-BaB2O4 or β-BaB2O4) is a versatile nonlinear optical crystal that offers many benefits and suits a wide range of applications owing to its several desirable features. It’s easy to see why it’s one of the most popular crystals in a wide range of domains.
Nonlinear beta-barium borate crystal is an excellent crystal for frequency-doubling (SHG) of Visible and Near IR laser light, OPO/OPG/OPA pumping by ultrafast pulses of wavelengths in the Near IR to UV, and sum-frequency mixing (SFM) into the Visible to the deep UV. BBO is one of the few practical crystals for use below 500 nm in SHG and SFM.
FEATURES OF OUR NONLINEAR BBO CRYSTALS FOR SALE
We delve into some of the most remarkable attributes of our nonlinear BBO crystals below:
- Wide transparency (in the region of ~190–3300 nm)
- Broad phase-matching range
- Large nonlinear coefficient
- Mohs hardness is equivalent to 4.5
- High damage threshold
- Wide thermal acceptance bandwidth
- High optical homogeneity
BBO crystal has broad tunability, a high damage threshold, and a 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 type II operation. BBO cannot be used for NCPM (temperature tuned) application. BBO is very good for tunable laser sources, such as ultrafast Ti:Sapphire or dye lasers.
