Beta Barium Borate (BBO) is a nonlinear optical crystal with a combination of unique features:

 

  • Wide transparency region
  • Broad phase-matching range
  • Large nonlinear coefficient
  • High damage threshold
  • Wide thermal acceptance bandwidth
  • High optical homogeneity

As a result of its excellent properties BBO crystal has a number of advantages for different applications, like NOPA with fsec pulses, harmonics generation (up to fifth) of Nd:YAG and Nd:YLF lasers, frequency doubling or tripling of femtosecond Ti:Sapphire and dye lasers, OPO at Type 1 and Type 2 phase-matching, E/O switching for Pockels cells and many other.

 

We offer:

  • BBO crystals with aperture up to 25×25 mm, length up to 25 mm
  • Thin BBO crystals down to 5 µm thick
  • AR, BBAR, P-coatings
  • BBO with gold electrodes for electro-optical (e/o) applications
  • Different mounting and repolishing services

 

Most of our standard crystals come mounted into open ring holders. Please note the letter "H" in the product code which indicates that crystal is supplied mounted.
