本文介绍了用锁模激光器(25p.s.)的单脉冲所产生的简并的四波混频;测量了它们的强度;证明了可以实现像的重建。此外还提供了脉冲持续时间、弛豫时间的测量方法。
This article describes the degenerate four-wave mixing produced by a single pulse of mode-locked laser (25 p.s.); measured their intensities; and demonstrated that image reconstruction is possible. In addition, it provides the pulse duration, relaxation time measurement method.
