LBO crystal

LBO crystal 2021-10-13T00:05:25+00:00


  • Broad transparency range from 160~2600nm
  • Large effective SHG coefficient
  • High damage threshold, High optical homogeneity
  • Wide acceptance angle and small walk-off
  • Spectral NCPM near 1300nm

LBO crystal is widely used broad optical transparency nonlinear optical material. Compared with other NLO crystals, such as DKDP, LBO has 3 times larger conversion coefficient. It is suitable for high power SHG applications because of minimal thermal lensing as compared to KTP.


  • SHG, THG of Nd lasers
  • SHG of Ti:sapphire, Cr:LiSAF and Alexandrite lasers
  • OPA and OPO, Pockels’ Cell
