介绍了一种基于掺镱光纤激光器的鲁棒自启动皮秒脉冲源。利用啁啾光纤布拉格光栅（C-FBG）进行色散控制，无需体色散补偿元件即可获得孤立锁模。采用半导体可饱和吸收器（SESAM）实现稳定自启动。产生3.6 ps脉冲，基本重复频率为45 MHz，平均输出功率为mW级，为1060 nm。基于修正的非线性薛定谔方程的详细数值模拟与实验结果吻合较好，可作为隔离锁模皮秒激光器的设计工具。所提出的设计可以简单地应用于全光纤环境稳定系统。(c) 2006 Elsevier B.V.版权所有
A robust, self-starting picosecond pulse source based on ytterbium (Yb3+) doped fiber laser is described. Utilizing a chirped-fiber-Bragg-grating (C-FBG) for dispersion control, solitary mode-locking is obtained without bulk dispersion compensation elements. A semiconductor saturable absorber (SESAM) is used for stable self-starting. 3.6 ps pulses are produced, with 45 MHz basic repetition-rate and mW scale average output power at 1060 nm. Detailed numerical simulations based on the modified nonlinear Schrodinger equation agree well with the experimental results and are used as a design tool for the solitary mode-locked picosecond laser. The presented design can be simply employed in an all-fiber environmentally-stable system. (c) 2006 Elsevier B.V. All rights reserved.
