Abstract

Laser ablation (i.e., the removal of target material upon irradiation) is under consideration; it is widely applied in some technologies. Physical models needed for an understanding of ablation have been developed since the invention of the first lasers. Some phenomena have been thoroughly investigated; however, there are still many problems that should be analyzed additionally. These poorly studied phenomena include surface structuring. The problems concerning ablation in liquid and laser forging/peening are not yet completely understood. They represent two sides of the same process: in the first case, the emphasis is on the description of motion of the substance beyond the target, whereas, in the case of laser forging, one abstracts from the plume and considers the elastoplastic transformations caused by a shock wave inside a target. The hydrodynamics of these processes differs radically with the transition from ultrashort to long pulses.

激光烧蚀：物理概念和应用（综述）

摘要

正在考虑激光烧蚀（即在照射时去除目标材料）；它在某些技术中得到了广泛的应用。自从第一批激光器的发明以来，已经开发出了用于理解消融所需的物理模型。一些现象已被彻底调查。但是，仍然有许多问题需要进一步分析。这些研究不足的现象包括表面结构化。关于液体和激光锻造/喷丸中的烧蚀的问题尚未完全理解。它们代表了同一过程的两个方面：在第一种情况下，重点是对物质超出目标的运动进行描述，而在激光锻造的情况下，则是从烟羽中抽象出来，并考虑了由下列原因引起的弹塑性转变目标内部的冲击波。
