摘要
本文提出一种简单的掺铒光纤激光器的结构,在室温下实现了稳定的双波长激光运转.在该结构中,使用刻写在保偏光纤上的光纤布喇格光栅作为波长选择器件.实验表明,通过调整偏振控制器的状态,在室温下能够得到稳定的双波长激光输出,波长间隔0.52nm,16次重复扫描对应于每一波长的振幅变化及波长间振幅差异均小于0.2dB.
Abstract
A simple erbium doped fiber laser configuration for achieving stable dual wavelength oscillation at room temperature is proposed. In this configuration, a fiber Bragg grating written in a polarisation maintaining fiber as the wavelength selective component is used. Stable dual wavelength oscillation with a wave spacing of 0.52nm at room temperature can be achieved through adjusting the state of polarization controller. An amplitude variation within 16 scans time is less than 0.2dB for both wavelengths.
