Brief
The article demonstrates a stable and versatile all-normal-dispersion mode-locked fiber laser built with a nonlinear amplifying loop mirror (NALM) and an angle-spliced polarization-maintaining (PM) fiber Lyot filter, enabling tunability of output spectral bandwidth (0.5 to ~4 nm) and allowing for continuously tunable single-wavelength and asynchronous dual-wavelength operation.
Summary
The paper presents a stable, all-PM mode-locked fiber laser that uses a tunable angle-spliced PM fiber Lyot filter instead of a standard filter. This allows for flexible control of output spectrum, enabling variable bandwidths (0.5 to ~4 nm), continuously tunable single-wavelength operation, and asynchronous dual-wavelength operation.
