| 中文摘要 | 提出一种基于相位采样的分布反馈式双波长光纤激光器,在不同的空间位置同时引入相位和采样周期的突变。通过理论分析,这种结构能够实现谐振腔的分离,使不同波长的光波利用不同空间位置的增益介质,克服增益介质均匀加宽引起的模式竞争,实现双波长激射。采用准分子激光器和均匀相位模板,在掺铒光纤上制作波长差为0.46nm的双波长光纤激光器,能够实现双波长激射。通过实验,对激光器输出功率和光栅强度的关系进行研究,表明输出功率和光栅强度成反比。; A dual-wavelength distributed feedback(DFB)fiber laser based on phase sampling is proposed and demonstrated.Change of phase and sampling period is introduced at different positions along a sampling Bragg grating.It is demonstrated theoretically that this structure can provide separate resonant cavities to overcome mode competition caused by gain homogeneous broading.A 0.46 nm-spaced dual-wavelength DFB fiber laser is achieved on an Er-doped fiber with excimer laser and homogeneous phase plate.Experiments shows that dual-wavelength lasing is achieved and laser power is in reverse proportion with coupling coefficient of the FBG. |
