激光振幅与位相涨落对阵列波导CO_2激光器输出光相干性的影响

Effects on the output beam coherence of the array waveguide CO_2 laser due to the fluctuation of the laser amplitude and phase

本文利用准单色光的相干理论,分析了阵列波导CO_2激光器输出同相态和反相态的原因,从而解释了相干态的持续时间,提出了两态的相互竞争现象是因激光器内部各种噪声造成的观点。有关的实验工作正在进行中。

The cause of the output state in phase and of opposite phase of the array waveguide CO_2 laser have been analyzed in this paper by utlization of the coherence theory for approximate plane-wave beam, furthermore the elucidation to the lasting time in coherent state has been made, and the view that the physical phenomenon of the state-competition between the state in phase and the state of opposicte phase is produced by the noises inside the laser has been presented now.Some relative experiments have been performing in our laboratory.
