Experimental study demonstrates stable dissipative soliton generation at 0.9 μm via an integrated Lyot filter, highlighting a compact, low-noise architecture for ultrafast fiber lasers.
We demonstrate a compact and low-cost 0.9 μm mode-locked neodymium (Nd)-doped fiber laser by integrating a polarization-maintaining (PM) Lyot filter into a figure‑9 nonlinear amplifying loop mirror (NALM) cavity. The filter is realized by angle-splicing of two fibers, enabling adjustable modulation depth. Stable dissipative soliton pulses are obtained at splice angles of 30° and 45°, with the 45° configuration delivering a pulse width of 8.31 ps, a pulse energy of 447 pJ, a signal-to-noise ratio of over 80 dB, and reduced phase noise. Numerical simulations of the Lyot-effect-based figure‑9 Nd-doped fiber laser were performed to analyze the influence of parameters such as the effective Lyot filtering strength and effective gain conditions on output pulse characteristics. The simulation results capture the main trends with experimental observations.
