通过用非线性薛定格方程处理光脉冲在钛宝石介质中的传播和独立计入四棱镜系统的色散 ,我们在自洽条件下对自锁模钛宝石激光器的脉冲性质进行了数值模拟计算。本工作的特点在于不断监视脉冲的演化过程并算到自洽为止 ,因而得到了稳定的脉冲及其宽度。结果表明 ,二阶色散补偿是必须的 ,而缩短介质长度比增大泵浦更易获得变换极限的脉冲。
By dealing with the propagation of optical pulses in the titanium sapphire medium with the nonlinear Schrödinger equation and the dispersion in the tetragonal prism system independently, we numerically simulate the impulsive properties of the self-locking Ti-sapphire laser under the self-consistent condition. This work is characterized by continuous monitoring of the evolution of the pulse and counting until it is consistent, resulting in a stable pulse and its width. The results show that the second-order dispersion compensation is necessary, while shortening the length of the medium is longer than pumping the pump to obtain the transformation limit pulse.
