| 摘 要： | 本文研究掺铒光纤激光器的瞬时变化特性以及动力学行为特点,分析了激光及光子数密度波动变化特点以及一级近似光子数密度波动函数.当泵浦起伏具有高斯白噪声特点时,泵浦起伏增加了激光的波动特性.在共振现象中,光子数密度的波动幅值随着离子浓度和光子寿命的增加而变大且激光的波动增强,但相对值却变小了.

| Abstract: | The instantaneous effect of and dynamics of Er-doped fiber laser is studied.The transient effect mechanism of Er-doped fiber laser under the pumping disturbance is a kind of forced vibration behavior.The paper gives the photon population density perturbations with time in Er-doped fiber laser and the fluctuation functions of photon population density are solved at the first order approximation When pumping perturbations have white noise characteristics,the dynamical characteristic of the laser is increased with pumping perturbations;the resonance absorption extent is widened,but it makes the stability of the laser reduced at the same time.This paper elaborates that the value of photon population density will increase along with the increase of the ion density and the photon life in the resonance phenomenon,and the unstability of the laser will be strong,but the opposite value will be diminished. |
