摘要 飞秒激光脉冲在空气中传输时产生独特的成丝现象,伴随着波长从紫外到中红外的超连续光谱辐射.高强度的光丝能继续与物质发生强烈的非线性相互作用,诱导多光子荧光和等离子体光谱等非线性光谱辐射.白光激光雷达以飞秒激光脉冲大气传输特性为基础,能提供多种遥感探测方法。文章阐述了飞秒激光脉冲成丝机理与白光激光雷达系统结构特点,介绍了国内外主要白光激光雷达的性能特点、白光激光雷达的主要探测方法与应用情况,最后分析了白光激光雷达的发展趋势。 High power femtosecond laser pulses undergo nonlinear filamentation in the atmosphere, with supercontinuum generation from the UV to the IR. Further more, the intense filaments can strongly interact with aerosols, stimulating nonlinear emissions like multiphoton-excited fluorescence or plasma emission. The white-light lidar, based on the properties of femtosecond laser pulses propagation, provides novel and multiple detection techniques. A brief review of the principle and applications of white-light lidar is presented. The theory about filamentation and structure of lidar are expounded. Characteristics of main white-light lidar systems reported so far in the world are introduced. The detection approaches and application examples are presented. In the end, perspectives for white-light lidar are analyzed.
