摘要
介绍了在特殊激光光束非线性传输特性方面的研究。主要包括具有横向效应的超短脉冲的时空演化、半导体量子阱系统的自诱导传输现象及电磁诱导透明介质中的共振多极矢量孤子。由于横向效应,包络面积为2nπ双曲正割脉冲在传输过程中会发生形变甚至分裂,随后发生月牙形脉冲的干涉,随着传输距离的增加干涉相长和自聚焦现象在横向轴上及其两侧出现。超短脉冲在量子阱中传输时,传统的面积定理失效,通过定义有效面积,实现了有效面积为2π的自感应传输。研究了四能级原子系统中共振多极矢量孤子的形成与传输,弱探测矢量场的两个偏振成分相互俘获,形成稳定的耦合态并实现了非常低的传输损耗。
Abstract
The studies on coherent control of extreme nonlinear optical properties via few-cycle laser pulses in atomic and atomic-like systems are reviewed,including self-focus effects on extreme nonlinear optics,self-induced transmission,resonant multipole vector solitons,etc. Due to the transverse effect,the 2nπ sech-pulse deformes and breaks up during the propagation. With further propagation,interference of the crescent-shape pulses,constructive interference and self-focusing phenomena are observed. Conventional area theorem is invalid in the study of ultrashort pulse in quantum wells. By defining effective area,the self-induced transmission of ultrashort pulse with effective area of 2π is investigated. The formation and propagation of resonant multipole vector soliton with weak light intensity are studied in a tripod-type atomic system,in which large nonlinearity and nearly vanishing absorption are achieved due to the quantum interference effect.
