Product overview
LBO or Lithium Triborate (LiB3O5) is an excellent nonlinear optical crystal. It has broad transparency range from 160nm to 2600nm, high optical homogeneity (dn > 10-6/cm), large effective SHG coefficient about three times greater than that of KDP crystal, and high damage threshold, good chemical and mechanical properties.Scitlion is able to offer
