摘要
基于非线性光学原理的光限幅技术作为一种被动式激光防护手段,近年来受到研究人员的广泛关注,光限幅材料是其核心器件。发展高性能光限幅材料对于构建应对日益严峻的高强度激光威胁的防护体系具有至关重要的意义。本文介绍了光限幅的基本原理,总结了基于不同非线性光学机制(如反饱和吸收、非线性散射、非线性折射等)的光限幅材料(包括有机小分子、金属配合物、碳基材料、半导体纳米材料等)的研究进展,提出了光限幅材料研究方向。
As a passive means of laser protection,optical limiting technology based on nonlinear optics has received extensive attention from researchers in recent years,and optical limiting materials are its crucial components.The development of high-performance optical limiting materials is of vital significance for the construction of protective systems to cope with the increasingly severe threat of high-intensity lasers.This review introduces the basic principle of optical limiting and summarizes the research progress on optical limiting materials(including organic small molecules,metal complexes,carbon-based materials,semiconductor nanomaterials,etc.)based on different nonlinear optical mechanisms(such as reverse saturable absorption,nonlinear scattering,and nonlinear refraction).Finally,future research directions for optical limiting materials are proposed.
