摘要
在非线性光纤环形镜非线性开关效应和块状半导体波导饱和吸收效应的共同作用下,实现了掺铒光纤激光器的自启动被动锁模,获得了十分稳定的锁模脉冲序列,观察到高次谐频锁模脉冲输出。分析了非线性光纤环形镜的非线性开关反射特性。
By using the nonlinear switching effect of nonlinear optical fiber loop mirror (NOLM) and the saturable absorption effect of bulk semiconductor waveguide selfstaring modelocking of erbiumdoped fiber laser has been demonstrated. High stable modelocked pulses train has been obtained. Harmonically modelocked pulses have been observed. The nonlinear switching reflection characteristic of NOLM is analyzed.
