摘要
随着超快激光应用需求的不断增长,激光控制技术正面临越来越多的挑战,超短脉冲操控研究亟待取得进一步的突破与发展.在激光器谐振腔增益、色散、损耗、非线性等效应共同作用下,多脉冲展现出比单脉冲更为丰富的动力学现象.研究表明其内部脉冲间距、相对相位、脉冲个数等参量具有高度可控性,为提升多脉冲的操控维度提供了新思路.本文从超快激光多脉冲的操控机理出发,介绍了多脉冲动力学、实时观测技术及激光器控制方法,重点综述了基于增益调制、偏振控制、色散调控、光机械效应等多脉冲操控方案,分析了各方案的性能,并展望了多脉冲操控技术的发展前景.
Abstract
The increasing demand for advanced applications of ultrafast lasers creates an urgent need to develop techniques for the on-demand manipulation of ultrashort pulses.In dissipative systems,multi-pulse structures,which suffer from composite-balance problems involving the gain/loss and dispersion/nonlinearity,yield versatile ultrafast soliton dynamics.Recent research indicates that various pulse characteristics,including the number of pulses,temporal separation,and relative phase,can be artificially manipulated,which leads to the concept of upgrading the on-demand manipulation of multi-pulse structures.Here,we first introduce the multi-pulse soliton dynamics and real-time spectral monitoring methods.Then,we review the approaches for artificially manipulating multi-pulse structures based on gain control,polarization control,dispersion control,and optomechanical effect.We also discuss their performances and corresponding application perspectives.
