  • LiB.sub.3 O.sub.5 crystal and its nonlinear optical devices
    Patent number: 4826283
    Abstract: This invention relates to NLO devices made of LiB.sub.3 O.sub.5 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.ANG. and tolerating larger processing error of crystals.
