    LBO Crystal Wide Transmission Band Good Ultraviolet Transmittance

    LBO is one of the excellent non-linear crystals in the ultraviolet band. It has been successfully used in second and third harmonic generation of YLF, YAG, YAP lasers. LBO crystal has wide transmission band, good ultraviolet transmittance, slightly deliquescence, good physical and chemical properties, moderate non-linear optical coefficient, good optical uniformity, high damage threshold, large allowable angle and small walk-off angle. It has been widely used in high average power second harmonic, sum frequency, difference frequency, third harmonic, fourth harmonic and parametric oscillation field

    LBO crystalthe most excellent nonlinear crystal for Noncritical Phase Matched laser frequency doubling

    The greatest advantage of LBO is that temperature tuning can be used to achieve non-critical phase matching (NCPM). When the non-critical phase matching relationship is satisfied in the frequency doubling process, the walk-off angle between the fundamental frequency light and the second harmonic of frequency doubling is 0. At this time, the effective length of LBO crystal can theoretically reach infinity, which can compensate for its small non-linear coefficient. Because its damage threshold is very large, it means that high-power fundamental wave pumping can be realized. Therefore, the conversion efficiency of fundamental frequency light will be greatly improved by using the non-critical phase matching of LBO crystal for the extra-cavity frequency doubling of pulsed laser. The beam quality and stability of frequency light will be greatly improved.
