摘要
飞秒激光在学术领域和工业领域都具有极高的应用价值,对飞秒激光进行准确快速的表征与精确控制对其各种应用至关重要.飞秒脉冲的传统表征方法依赖非线性效应且光路结构复杂,而飞秒脉冲的控制则大多采用开环手动调试,无法实现稳定的最优调控,极大地限制了飞秒激光的应用.近年来,智能技术的出现给飞秒激光研究提供了新范式,结合智能技术,低能量高重复频率飞秒脉冲序列的单帧全域测量与飞秒脉冲的按需智能调控有望成为现实.
Abstract
Femtosecond lasers have extremely high application value in both academic and industrial fields.Accurate and rapid characterization,as well as precise control of femtosecond lasers,hold vital position in their diverse applications.Conventional characterization methods for femtosecond pulses rely on nonlinearities thereby involving complex optical setups.The control over femtosecond pulses often relies on open-loop manual tuning,where the stable optimal control is not guaranteed.As a result,the application of femtosecond lasers is greatly limited.In recent years,the emergence of intelligent technologies has provided a new paradigm for femtosecond laser research.Through introducing intelligent technologies properly,the single-shot full-field characterization over the low-energy,high-repetition-rate femtosecond pulse train and the on-demand intelligent control over femtosecond pulses can be expected in the future.
