BBO crystal

BBO crystal 2021-10-20T23:19:11+00:00


  • Broad phase matching (SHG) range
  • Wide transimisson region from 190~3500nm
  • Large effective SHG coefficient
  • High damage threshold, High optical homogeneity
  • Good mechanical and physical properties

BBO is used in various NLO applications such as OPO, OPA. BBO is broadly used because of its wide transparency and phase matching ranges, large non-linear coefficient, perfect optical homogeneity and high damage threshold. Large range of thermal acceptance, high damage threshold and small absorption coefficient makes BBO a good solution for frequency conversion in high average power laser systems.
