摘要

利用掺铒光纤环形激光器非线性克尔效应模型，研究抽运功率和非线性系数对激光器输出混沌信号带宽的影响.研究表明：在非线性系数一定的情况下，混沌带宽随着抽运功率的增加先增大后减小；固定抽运功率为01 W，当非线性系数增加到45 W-1km-1时，掺铒光纤激光器输出的混沌带宽达到最大值（153 GHz），非线性系数继续增加，输出混沌的带宽将逐渐减小.

Based on nonlinear Kerr effect model of erbium-doped ring fiber laser, the influences of pump power and nonlinear coefficient on chaotic bandwidth are investigated. The results indicate that, with fixed nonlinear coefficient, the bandwidth of the chaos increases first and then decreases with the increasing of pump power. Fixing the pump power at 01 W, the chaotic bandwidth rises up to 153 GHz with the nonlinear coefficient increased to 45 W-1km-1. On further increasing the nonlinear coefficient the chaotic bandwidth is reduced gradually.
