最近几年的研究表明，时间分辨数字全息术将传统的离轴数字全息术与超短探测激光脉冲相结合，形成了一种适合研究超快现象的通用工具。这种方法的时间分辨率取决于所使用的超短探测脉冲的持续时间，并且可以在类似于20FS到类似于10 ns的时间范围内进行测量。本文综述了飞秒脉冲的特性及其在激光微细加工中的应用，如飞秒脉冲在透明固体中的成丝、飞秒脉冲对薄膜的损伤以及单脉冲和双脉冲飞秒激光烧蚀。
During the last years it was shown that time-resolved digital holography (TRDH), combining the conventional off-axis digital holography and ultrashort probing laser pulses results in versatile tool suitable for ultra-fast phenomena studies. The temporal resolution of this method depends on the duration of the used ultrashort probing pulses and measurements could be performed in temporal range from similar to 20 fs to similar to 10 ns. We review features of TRDH with femtosecond pulses and its applications for the investigation of such processes occurred or used in laser micro fabrication as femtosecond pulse filamentation in transparent solids, thin film damage by femtosecond pulses and one and double pulse femtosecond laser ablation.
