  • METHOD FOR IMPROVING INTENSE LASER-INDUCED DAMAGE RESISTANCE OF NONLINEAR SYNTHETIC CRYSTALS
    Publication number: 20250333879
    Abstract: The invention belongs to the technical field of nonlinear synthetic crystals, and particularly relates to a method for improving the intense laser-induced damage resistance of nonlinear synthetic crystals. The method comprises: electrifying nonlinear synthetic crystals by means of a stabilized DC power supply under a certain atmosphere. The invention can effectively decrease the density of pinpoint damage in nonlinear synthetic crystals by means of an “electrification method”, thus optimizing the intense laser-induced damage resistance of the nonlinear synthetic crystals and particularly fulfilling a more obvious improvement effect on defects with a greater damage threshold. The electrification method provided by the invention is expected to further reduce the damage probability in a case where an ultraviolet nanosecond pulse laser fluence with a wavelength of 355 nm or 351 nm is greater than 8J/cm2 to improve the damage resistance of crystals.
