| 摘 要： | 在高频及低频脉冲种子光的情况下讨论了掺镱双包层光纤放大器的输出特性.在有限差分法中,对于不同重复频率的脉冲种子光,需要设置不同的初始条件以快速计算得到稳定输出.本文给出了在高频和低频情况下设置初始条件的方法,并讨论了作为种子光的准连续高频高斯脉冲峰值功率与其等效连续光功率之间的关系,最后计算了种子光为高频及低频脉冲情况...

| Abstract: | Output characteristics of Yb-doped double-cladding pulsed fiber amplifiers were discussed under conditions of low and high repetition rates using the time-dependent rate equations.Because there are several different initial conditions used in the finite-difference method with different repetition rates,some methods were presented to determine the initial conditions.The relationship of the peak powers of the high repetition rates with their equivalent continuous wave powers was also discussed when the signal... |
