Four-wave mixing and phsae conjugated wave generation in a semiconductor diode laser

本文提出了一种从半导体激光器中发生和检测相位共轭光的新方法,并用1.3μm分布反馈半导体激光器作了实验验证。本方法不仅可以用来发生相位共轭光,还可以用来研究振荡运转中的激光激活介质的非线性光学特性。

A new method was proposed for tha generation and detection of phase conjugated optical waves from a semiconductor diode laser using a smith-type interferometer. This method has an advantage to display the spatial as well as tamporal information of the generated phase conjugated optical waves. The experimental demonstration was performed by using a 1.3μm DFB diode laser, and a remarkable agreement was confirmed between experimental and theoretical results. The present method can be generally applied bo all kinds of lasers for the generation of phase conjugated waves as well as for the study of their nonlinear optical properties during the laser oscillation.
