摘　　要：为了获得高峰值功率与窄脉宽的激光脉冲,本文使用速率方程和功率传输方程建立了掺镱光纤激光器调Q锁模仿真模型,并且研究了输出脉冲随Q开关上升时间和泵浦功率的演变。通过优化上升时间和泵浦功率,可得到明显的调制锁模脉冲,并且输出脉冲的峰值功率高达15000W。In order to realize laser pulse with high peak power and narrow pulse width, we propose an Q switching and mode locking simulation model for ytterbium-doped fiber laser, output pulse with different rise time of Q-switching and pump power is demonstrated. With optimized rise time and pump power, output pulse with obvious Q switching and mode locking is obtained and the peak power of the output pulse is as high as 15000 watts.
