| 摘 要： | 在柱对称条件下，利用耦合的布洛赫－麦克斯韦方程，研究了激光脉冲在原子蒸气介质中的共振传播。考察了脉中在时空中的演化。数值计算结果表明激光脉冲在传播中，由于自感应透明与光波的衍射效应，表现出复杂的相干现象。

Spatial-Temporal Properties of Laser Pulse Propagating in Resonant Atomic Vapor |
| |
| Abstract: | When cylindrical symmetry is assumed, a numerical study of coherent on-resonance propagation of laser pulses in atomic media has been done based on the coupled Bloch-Maxwell equations. The spatial-temporal evolution of the laser pulse was studied in consideration of both the self-induced transparency and diffraction. The numerical results show that the pulses display complicated coherent phenomena. |
