文摘
This paper describes a dual-wavelength demonstration for a proposed ytterbium-doped fiber laser in the 1 μm region. A microfiber and a D-shaped fiber, functioning as a wavelength selective filter, is inserted into the laser ring cavity setup to ensure a stable dual wavelength operation. The dual-wavelength output from both the microfiber and the D-shaped fiber possess a wavelength spacing of 4.01 and 4.62 nm, respectively. Both the microfiber and D-shaped fiber use the ytterbium doped fiber as gain medium, and has a stable peak power and side-mode suppression ratio of more than 30 dB.
