易于开启和维持自锁模的适度失谐腔克尔介质自锁模激光器

An Easier Starting and Maintaining Self-mode-locked Kerr Medium Laser with a Suitably Detuned Cavity

提出工作于谐振腔适度失谐时的克尔介质自锁模激光器易于开启和维持自锁模的理论。根据克尔镜锁模原理和动态可饱和高斯增益特性，利用激光传输矩阵理论，对系统进行了数值模拟计算，确证了最佳腔镜失谐角的存在．结论与已有的实验结果相符，并对它们赋予了新的合理解释。

This paper shows theoretically for the first time that the starting and maintaining of the self-mode-locking of a Kerr medium self-mode-locked laser (KMSMLL) can be made more easily by rationally controlling the parameters of the detuned cavity. According to the properties of the KMSMLL such as the Kerr lens mode-locking (KLM) and the dynamic saturable Gaussian gain, using the laser ray propagational matrix, we calculated the KMSMLL numerically and obtained the most suitable detuning angle of the cavity mirror.The theory agrees with some experimental results and gives new and rational explanations.
