再生锁模激光系统的定态输出及其稳定性

Steady-state output and its stability in regeneratively mode locking lasers

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.

Three autonomous equations for pulse parameters were deduced by substituting quasi-soliton solution to the master equation of regenerative mode locking lasers. The steady-state solutions without and with chirp were derived and their stability was analyzed by the method of linear stability analysis. The results show that the evolution of the steady-state output parameters of the system varies with the values of modulation parameters, group velocity dispersion and self phase modulation. Thus the steadystate output can be controlled by adjusting the modulation parameters in the system.
