摘要

分析了谐振和准谐振类孤子激光脉冲在非平衡介质中的超光速传播。结果表明，这种脉冲是不稳定的。然而，由于重塑机制，在不稳定发展的初始阶段可以观察到这些脉冲剖面的超光速传播。

Superluminal Objects in Non-Equilibrium Media

An analysis is performed of the superluminal propagation of resonant and quasi-resonant soliton-like laser pulses in non-equilibrium media. It is shown that such pulses are unstable. However, the superluminal propagation of these pulse profiles can be observed at the initial stage of an instability’s development, due to the mechanism of reshaping.
