克尔锁模Cr4+:YAG激光器的理论分析
Theory of Kerr-Lens Mode-Locked Cr4+:YAG Laser
摘要
从传统的ABCD规律出发,用扩展的非线性介质传输矩阵详细分析了克尔自锁模Cr4+:YAG激光器激光介质中的光斑变化.结果发现,虽然半导体可饱和吸收镜(SESAM)的引入使两臂的等效长度不再相等,从而破坏了稳区的连续性,却增强了激光器的非线性效应,使锁模脉冲更易得到.实验得到的最大谱线展宽为40 nm.
Abstract
Based on the traditional ABCD law, the relative variation of spot size in the laser medium is analyzed. The results show that the introduction of SESAM destroyed the continuity of the laser stability and enhanced the nonlinearity of the laser. So the mode-locked pulses are generated easily due to the SESAM. The spectrum width of 40пш has been obtained experimentally.
