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