Abstract

Four-wave mixing with optical pulses is considered analytically. It is shown that, whereas true time reversal of an amplitude pulse is not possible with continuous-wave pumping, this can be achieved by short-pulse pumping of a long, narrow, nonlinear medium, although time-dependent phase variations are not time reversed.

摘要

对光脉冲的四波混频进行了分析研究。结果表明，虽然连续波泵浦无法实现幅度脉冲的真正时间反转，但通过对长而窄的非线性介质进行短脉冲泵浦可以实现这一点，不过与时间相关的相位变化不会发生时间反转。
