| 摘 要： | 对自锁模掺钛宝石激光器的原理作了较详细的描述，指出克尔透镜效应是形成自锁模的主要原因，但是，只有将克尔透镜自聚焦、振荡光参数和泵浦光参数三者结合起来考虑，才能全面了解自锁模的形成过程，本文从速率方程出发，得出了激光介质增益与光束参数的相对变化曲线，并据此来优化自锁模钛宝石激光器的设计，最后，将计算结果与实验作了比较，两者符合得较好。

| Abstract: | Self-focussing by a Kerr nonlinearity in combination with an intracavity aperture creates a power-dependent amplitude modulation in Ti:sapphire lasers.It has been used as a method of self-mode-locking for generating femtosecond pulse.The general features of this mode-locking technique is described and a new,simple model is developed for the optimization of Kerr-lens-mode-locking performance by taking account of gain modulation created by pump beam in conjuction with laser beam.Theoretical prediction is confirmed by experimental measurement. |
