BBO crystals
Main features
- Broad transparency range from 188 nm to 5.2 µm (reasonable @ 3 µm - 5,2 µm for few tens of µm thick crystals)
- Broad phase-matchable range for various second order nonlinear interactions over almost entire transparency range
- High nonlinear coefficient, especially in the UV region compared to other nonlinear crystals
- Wide thermal acceptance bandwidth
- High damage threshold
Application examples
- Harmonic generation (up to fifth) of Nd:YAG, Nd:YLF lasers and other Nd-doped laser crystal based lasers
- Frequency doubling, tripling of femtosecond Ti:Sapphire, Dye lasers
- Optical parametric amplification and frequency up-conversion
- Characterization of ultrashort laser pulses (FROG, XFROG, SPIDER, dispersion scan, chirp scan)

BBO crystal posseses broad transparency range from 185 nm to 3,3 µm for few millimiters thick crystals and reasonable transparency range from 3 µm to 5,2 µm for few tens of µm thick crystals. It is an attractive solution as a nonlinear crystal, since it provide phase-matching conditions for various second order interactions almost over entire transparency region.
