Abstract

In this paper, the nature of the crystalline phases observed at the surface damage sites resulting from laser irradiation is investigated by X-ray diffraction. The results are compared against new data on thermal decomposition of KDP salt. The damage sites consist of polycrystalline KDP and partially dehydrated phases. The comparison with the thermal decomposition study allows to assign a temperature range to the overall temperature reached by the surface during the damaging process. Finally, the difference between surface damage and bulk damage is discussed.
激光致KDP晶体损伤的热机制
本文用x射线衍射研究了激光辐照后表面损伤部位的结晶相性质。结果与KDP盐热分解的新数据进行了比较。损伤部位由多晶KDP相和部分脱水相组成。与热分解研究的比较允许为表面在破坏过程中达到的总体温度指定一个温度范围。最后,讨论了表面损伤与本体损伤的区别。
