All-Polarization Maintaining Noise-Like Pulse From Mode-Locked Thulium-Doped Fiber Laser Based on Nonlinear Loop Mirror
In this paper, we present a figure-eight all-polarization maintaining thulium-doped mode-locked fiber laser based on a nonlinear optical loop mirror Baseball operating at noise-like pulse regimes.The total cavity length is 34.5 m, and the calculated net group delay dispersion is estimated to be ∼−2.616 ps2.At the maximum pump power, s
