| Abstract: | A kind of narrow-line fiber laser technology utilizing fiber Bragg gratings is described. The methods of getting monomode laser output and improving output power are discussed in this paper. The recent advances are presented, especially the latest data of Er:Yb codoped DBR fiber laser. The critical techniques such as fiber doping, photosensitivity of fiber and fiber grating writing are discussed as well. A monomode Yb fiber laser is also presented as an ideal seeder laser for the high power laser system. |
