LBO (LiB3O5) is an excellent nonlinear optical crystal. It's phase matchable for the SHG and THG of Nd:YAG and Nd:YLF lasers, using either type I or type II interaction. LBO is a nonlinear optical crystal perfectly suited for harmonic generation as well as sum frequency mixing and OPO applications using widely spread Nd lasers, Ti:Sapphire and Dye lasers. Such physical LBO properties as excellent optical homogeneity, non-hygroscopicity and very high damage threshold assure long and stabile operation of crystal. LBO crystal is the first choice as harmonic generator of high-peak power pulsed lasers.
