BBO crystals

Main features

 

  • Broad transparency range from 188 nm to 5.2 μm (reasonable transparency @3 μm - 5,2 μm for few tens μm thick crystals)
  • Broad phase-matchable range for various second order nonlinear interactions over almost entire transparency range
  • Wide thermal acceptance bandwidth
  • Highest nonlinearity of all UV nonlinear crystals
  • High laser induced damage threshold
  • Ultrathin crystals available for ultrafast (<10 fs) applications
  • Custom crystals available upon request

 

Application examples

 

  • Harmonic generation (up to fifth) of pulsed Nd-doped laser crystals
    based lasers
  • Frequency doubling, tripling of pulsed Ti:Sapphire, Yb-doped, dye lasers
  • Widely tunable type I and II optical parametric oscillators
  • Characterization of ultrashort laser pulses by FROG, XFROG, SPIDER,
    dispersion scan, chirp scan methods

BBO crystals possess transparency range from 188 nm to 5,2 μm, which includes reasonable transparency from 3 μm - 5,2 μm for few tens μm thick crystals, while their phase-matchable range spans almost over entire transparency range. Combined with other magnificent properties of BBO, it is favorable to use them for numerous nonlinear parametric applications, e.g. harmonic generation of pulsed Nd-doped crystals based lasers and frequency doubling, tripling of Ti:Sapphire lasers, widely tunable type I and II OPOs. It is worth to mention that BBO crystal has highest nonlinearity among UV nonlinear crystals.
