材料加工，主要是微加工中的许多应用正促进高重复率飞秒激光的研制。从物理学角度看，这种加工能定义为薄表面层材料的激光烧蚀，与周围物质没有明显的热交换。在金属中激光脉冲通常被电子吸收。在几皮秒时间内这些电子将它们的能量传输给晶格。在非金属（例如半导体和电介质 Many applications in material processing, mainly micromachining, are driving the development of high repetition rate femtosecond lasers. From a physical point of view, this process can be defined as laser ablation of thin surface layer materials with no significant heat exchange with the surrounding material. Laser pulses in metals are usually electronically absorbed. Within a few picoseconds, these electrons transfer their energy to the lattice. In non-metallic (such as semiconductors and dielectrics
