摘要

以提高磷酸盐激光钕玻璃耐热冲击性能为目的,研究了一种用碱和酸缓冲液相结合处理磷酸盐激光钕玻璃表面的方法。通过对比该方法与303砂细磨、混合强酸处理和化学机械抛光3种方法处理后的表面形貌和机械性能,发现该表面处理方法可以减少玻璃表面的显微缺陷,从而显著提高表面显微硬度、抗折强度。实验结果表明采用该表面处理方法可提高磷酸盐激光钕玻璃在重复频率氙灯抽运下的热破坏阈值和激光效率。

Abstract

In order to improve heat shock resistance of phosphate laser glass,a surface strengthening treatment method with base and acid buffer solutions is studied. Evaluated from surface morphology and mechanical property of phosphate laser glass,it is demonstrated that this method is better than fine ground with 303 abrasive,surface treatment in strong mixed acid,and chemical-mechanical polishing. The results indicate that this method is more efficient to remove the surface drawbacks .Phosphate laser glass which is treated by this method presents higher surface micro-hardness and higher flexural strength as well. Experimental resultshows that the thermal damage threshold and laser efficiency of surface strengthened phosphate laser glass is improved when it is pumped with flashlamp in repetition frequency.
