Kelly sideband suppression and wavelength tuning of a conventional soliton in a

We demonstrate a stable conventional soliton in a Tm-doped hybrid mode-locked fiber laser by employing a homemade all-fiber Lyot filter (AFLF) and a single-wall carbon nanotube. The AFLF, designed by sandwiching a piece of polarization-maintained fiber (PMF) with two 45° tilted fiber gratings inscribed by a UV laser in PMF with a phase-mask scanning technique, shows large filter depth of ~9 dB and small insertion loss of ~0.8 dB. By optimizing the free spectral range of the AFLF, the Kelly sideb
