| 摘 要： | 本文综合考虑了在(3+1)维负色散介质中Kerr效应、衍射、色散对光脉冲传输的影响,用变分原理和数值计算的方法对带啁啾高斯光束的传输特性进行了研究,讨论了非线性时空耦合参数,初始束宽、脉宽、散聚特性对时空“自聚焦”特性的影响,计算表明利用会聚光束在负色散克尔介质中传输的耦合作用,可以压缩脉宽,这可作为一种新的压缩脉宽的方法。

| Abstract: | In this paper,the influences of Kerr effect,diffraction and dispersion effect on propagationproperties of a light pulse in 3+1 dimensional abnormal dispersive medium are studied.The propagationproperties of Guassian beam with chirp are studied by using variational principles and numericalmethod.The impacts of initial pulse width,beam width,chirp and spatial-temporal coupling characteron“self-focusing”properties are discussed. |
