Abstract.  The output properties of the 980-nm Yb-doped fiber laser versus pump power and core–cladding ratio of gain fiber, also the amplified spontaneous emission (ASE) at different wavelengths of seed laser, are investigated theoretically. An all-fiber amplifier based on different wavelengths of seed laser at 974.4, 977, and 981.7 nm brings the studies on parasitic oscillation and ASE in the 980-nm Yb-doped fiber amplifier. Through the theoretical and experimental research, we found that the controlling of three-level ASE around 980-nm is pivotal for obtaining a high-power 980-nm Yb-doped fiber amplifier.
