Tunable Broadband Single-frequency Narrow-Linewidth Fiber Laser

by Laser Explorer Posted on 244 views 0 comments
Abstract The tunable single-frequency (SF) narrow-linewidth fiber laser with all-fiber complex cavity structure is designed, which is composed of an optical fiber tunable filter, a high-precision ring filter, and a fiber loop mirror. A 980-nm semiconductor laser is used as the pumping source, and the ytterbium-doped fiber is employed as the gain medium and saturable absorber, ...
