LiB3O5 crystal and its nonlinear optical devices

摘要

This invention relates to NLO devices made of LiB3O5 crystals, which can be used in a laser system of high power density and relatively large divergence and possess a character of high SHG conversion efficiency. Moreover the NLO devices (including waveguide devices) of this invention are capable of producing coherent harmonics of wavelength below 2000 ANGSTROM and tolerating larger processing error of crystals.
