本文提出了一个ABCD矩阵模型，表明在连续泵浦Ti：Al（2）O（3）激光器中，激光棒中的自聚焦导致高斯光束参数的改变。自锁模的稳定性应来自这些光束扰动。支持这个模型的光束修改的实验测量。研究了增益引导的作用，并讨论了该模型的局限性。
We present an ABCD matrix model showing that self-focusing in the laser rod leads to modifications of the Gaussian beam parameters in cw-pumped Ti:Al(2)O(3) lasers. Stabilization of self-mode-locking should result from these beam perturbations. Experimental measurements of beam modifications supporting this model are presented. The role of gain guiding is studied, and the limitations of the model are discussed.
