摘要
从啁啾脉冲放大技术到精密光谱学光频梳,从超分辨荧光显微术到飞秒化学,这些(分别获得2018、2005、2014、1998年度诺贝尔物理奖和化学奖)举世瞩目的科学成就,无不彰显了超短脉冲激光对人类科技创新和认知力的深远影响。对超短脉冲激光的特点、表征方法、产生与放大途径等一些重要基础知识进行回顾,对用于先进制造业中的超短脉冲激光系统的基本光学结构、各种主要技术指标及实际工业加工应用中一些关键激光参数的合理选择予以介绍。最后还呈现一幅在多年教学实践基础上绘制的“超快激光光学”学习路线图,并以此作为对超短脉冲激光相关科学技术知识框架的一种整体描绘。
Abstract
Ultrashort pulse (USP) lasers have spearheaded great innovations in science and technology, as evidenced in their wide range of applications from chirped pulse amplification to optical frequency comb-associated precision spectroscopy and from super-resolution fluorescence microscopy to femtosecond chemistry. These outstanding scientific achievements (respectively awarded by the 2018 and 2005 Nobel Prizes in Physics, and 2014 and 1998 Nobel Prizes in Chemistry) have sufficed to evidence the profound and far reaching influence of USP laser on the innovations of science and technology, and the cognitive power of humankind. Herein, we review some of the fundamental knowledge regarding the main characteristics, characterization methods, and generation and amplification methods of USP lasers. Specifications and optical schematics of industrial USP laser systems, as well as the subject of how to select USP laser parameters for practical applications, are specially discussed. A pedagogical “ultrafast laser optics” learning map is also introduced for providing an overall picture of this fast advancing and extremely fascinating field.
