超光速光学相位共轭：脉冲整形和不稳定性
Superluminal Optical Phase Conjugation: Pulse Reshaping and Instability
摘要：
从理论上研究了光学相位共轭器对入射探测脉冲的响应。在光学相位共轭器的稳定（亚阈值）操作制度中，可以发射具有超光超前峰值的探测脉冲，而共轭反射总是亚光的。在不稳定的（阈值以上）制度，超光速响应发生在反射和透射，在时间之前的指数增长的发病，由于不稳定性。
英文摘要：
We theoretically investigate the response of optical phase conjugators to incident probe pulses. In the stable (sub-threshold) operating regime of an optical phase conjugator it is possible to transmit probe pulses with a superluminally advanced peak, whereas conjugate reflection is always subluminal. In the unstable (above-threshold) regime, superluminal response occurs both in reflection and in transmission, at times preceding the onset of exponential growth due to the instability.
