Abstract

In this paper, we have studied ML features in a sub-200-fs erbium-doped all-fiber laser based on a saturable absorber obtained by high-pressure-high-temperature treatment of commercially available single-walled carbon nanotubes. We have shown that there is a significant effect on the ultrafast optical properties of saturable absorber due to the high-density well-aligned structure of newly-developed single-walled carbon nanotubes and related it to the mode-locked laser performance. We have obtained a low-intensity-noise ultra-short stretched pulse generation with a repetition rate of 42.22 MHz, a spectral pulse width of 30 nm, and average output power of 11.3 mW with long-term stability of ~ 0.06% during 3 h measurement time
