摘要
介绍了一种全光纤窄线宽脉冲激光器。该激光器由两部分组成,即脉冲光纤激光器种子和由隔离器、耦合器以及光纤光栅组成的窄线宽脉冲提取装置。脉冲光纤激光器种子是基于半导体可饱和吸收镜(SESAM )为锁模机制的全光纤被动锁模激光器,输出脉冲的光谱宽度约为3 nm。窄线宽脉冲提取部分对脉冲光纤激光器种子输出脉冲的光谱进行提取、窄化,输出脉冲的光谱宽度约为0.1 nm。该激光器操作简单、设备简易,为全光纤结构;不仅可以输出窄线宽光脉冲序列,而且同时还可以输出脉冲光纤激光器种子的光脉冲序列,极大地拓展了脉冲光纤激光器的应用范围。
Abstract
An all-fiber pulsed laser with narrow line width is introduced. The fiber laser consists of a pulsed fiber laser seed and a narrow line width abstraction device. The all-fiber pulsed laser seed is based on a semiconductor saturable absorber mirror (SESAM) with a 3-nm line width. Including an isolator, a coupler and a fiber Bragg grating the narrow line width abstraction device extracts narrow line width optical pulses from seed laser′s optical pulses and produces optical pulses with a 0.1-nm line width. The all-fiber, easy using, simple configuration, pulsed fiber laser can not only output narrow line width optical pulses, but also output the wide line width optical pulses from the pulsed fiber laser seed simultaneously, which greatly broadens the applications of the pulsed fiber lasers.
