BBO crystal transparency ranges from 188 nm to 5,2 µm, which includes reasonable transparency from 3-5,2 µm for few tens µm thick crystals, while their phase-matchable range spans almost over the entire transparency range. Combined with other magnificent properties of BBO, it is favorable for numerous nonlinear parametric applications, e.g. harmonic generation of pulsed Yb-doped crystal-based lasers and frequency doubling, a tripling of Ti:Sapphire lasers, widely tunable type I and II OPO. It is worth to mention that BBO crystals have the highest nonlinearity in the UV range out of all common nonlinear crystals.
Application examples
- Harmonic generation (up to fifth) of pulsed Nd-doped crystal-based lasers.
- Frequency doubling, a tripling of pulsed Ti:Sapphire, Yb-doped, dye lasers.
- Widely tunable type I and II OPO.
- Characterization of ultrashort laser pulses by FROG, XFROG, SPIDER, dispersion scan, chirp scan methods.
