BBO (Nonlinear Crystal)

β-BaB2O4 (BBO, Barium Metaborate) is a widely used nonlinear crystal for frequency conversion in the UV, visible and NIR. It has the following characteristics:

  • large birefringence
  • Low dispersion
  • High damage threshold
  • Wide phase-matching range
  • Good temperature stability
  • Large nonlinear optical effects
  • A frequency multiplication factor six times higher than that of KDP crystals

BBO crystal can be used in high, precise and advanced laser technology fields of research and development. These fields include all-solid-state tunable Laser, ultrafast pulsed Laser, deep ultraviolet Laser, etc. It is also used for the following purposes:

  • Nd:YAG and Nd:YLF lasers for frequency doubling
  • Tripling and mixing of dye lasers
  • Ti:Sappire and Alexandrite lasers for frequency doubling
  • Tripling and quadrupling
  • Optical parametric amplifiers (OPA)
  • Optical parametric oscillators (OPO)
  • Argon ion, ruby and Cu vapor lasers for frequency doubling

 

The features of BBO crystal:

  • Good physical properties
  • Appropriate mechanical properties
  • Temperature bandwidth about 55°C
  • High optical uniformity: δn≈10-6/cm
  • Transmission range from 190 nm to 3500 nm
  • Phase matching range from 6 nm to 3500 nm
  • Large effective SHG (second harmonic generation) coefficient
  • 100 ps pulse damage threshold of 10 J/cm2 at 1064 nm
