Laser modification method of transparent ceramic and transparent ceramic
The invention relates to a laser modification method of transparent ceramic and the transparent ceramic obtained by the method, and the method combines laser pretreatment (LPP) and laser shock peening (LSP) to improve the laser damage resistance (LIDT) and mechanical stability of the transparent ceramic. The technical scheme comprises step-by-step surface and deep layer laser treatment, LPP is executed preferentially to eliminate surface microdefects and improve optical transmittance and damage threshold, and then the mechanical damage resistance of the interior of the material is enhanced through the LSP technology under the condition that the laser energy density is kept lower than the safety threshold. Through strict LIDT and mechanical property tests, technological parameters are fed back and adjusted, and the performance of the transparent ceramic is comprehensively improved. The process is suitable for high-performance optical elements and laser systems requiring high optical transparency and excellent mechanical properties. The innovation not only obviously prolongs the service life of the material, but also reduces the maintenance cost, and has wide application prospects.
本发明涉及一种透明陶瓷的激光改性方法及该方法得到的透明陶瓷，该方法通过结合激光预处理(LPP)与激光冲击强化(LSP)的方法，改善透明陶瓷的抗激光损伤能力(LIDT)及其力学稳定性。该技术方案包括逐步的表面与深层激光处理，优先执行LPP以消除表面微观缺陷并提升光学透过率和损伤阈值，随后通过LSP工艺在保持低于安全阈值的激光能量密度下，加强材料内部的抗机械损伤性能。通过严格的LIDT与力学性能测试，反馈调整工艺参数，实现对透明陶瓷性能的全面提升。该工艺适用于需要高光学透明度与优异力学性能的高性能光学元件和激光系统。此项创新不仅显著提升了材料的使用寿命，还降低了维护成本，具有广泛的应用前景。
