将准孤子解代入再生锁模激光系统的主方程,推导出脉冲参量的三个自治微分方程.求解了无啁啾和有啁啾两种情况下系统的定态解,并分析了其稳定性.研究表明,系统的定态输出随系统的调制深度或调制频率、群速色散或自相位调制等参量值的变化而变化.因此,通过调制系统的参量可以控制激光系统的定态输出.
The quasi-solitons are solved into the main equation of the regenerative mode-locked laser system, and three autonomic differential equations of the pulse parameters are deduced. The steady-state solutions of the system under both chirp and chirp are solved and the stability of the system is analyzed The research shows that the steady state output of the system varies with the modulation depth or modulation frequency of the system, the group velocity dispersion or the self - phase modulation, and so the output of the laser system can be controlled by modulating the parameters of the system.
