研究脉宽分别为30fs,300fs,3000fs的激光作用到熔石英晶体上的烧蚀阈值，可以提高材料的加工精度，促进激光加工技术的实用化。结果表明：在超短脉冲时，烧蚀阈值可以精确确定，并且烧蚀阈值偏离与脉冲间隔平方根成正比的规律，烧蚀阈值与激光的脉冲宽度无关。文中结果与以前研究结果符合得较好。
研究脈寬分彆為30fs,300fs,3000fs的激光作用到鎔石英晶體上的燒蝕閾值，可以提高材料的加工精度，促進激光加工技術的實用化。結果錶明：在超短脈遲時，燒蝕閾值可以精確確定，併且燒蝕閾值偏離與脈遲間隔平方根成正比的規律，燒蝕閾值與激光的脈遲寬度無關。文中結果與以前研究結果符閤得較好。

Theoretical study of ablation threshold in fused silica by 30fs, 300fs, 3000fs laser pulse, from which can obtain the more precise processing and put the laser processing into practice. Analyzing the results, the authors know that ablation threshold can be definited exactly and deviation from direct ratio regularity of square root. The authors find that ablation threshold has nothing to do with laser pulse-width. Present results are in quantitative agreement with the previous studies.
