摘要

利用密度矩阵方程和麦克斯韦传播方程的耦合并且考虑激光脉冲的横向效应, 在柱对称的条件下, 研究了两束脉冲在级联系统中的共振传播, 考察了脉冲在光学厚介质中的时空演化过程。 数值计算中考虑了两个上能级的自发辐射速率, 给出了脉冲能量的空间演化及电离粒子在空间的分布。

Abstract

Based on the coupled matrix-density equations and Maxwell equations and considered the transverse effect of the laser pulses, resonant propagation of two laser pulses in three-level ladder system was presented under the cylindrical symmetry. The evolutions of pulses propagating in thick absorbers were studied. The spontaneous relaxation of upper levels is considered in numerical solutions. The calculation results show the evolution of pulse energy and the distribution of ionization particle.
