A Passively Mode-Locked Erbium-Doped Fiber Laser Based on a Single-Wall Carbon Nanotube Polymer

Soliton fiber laser mode-locked by a single-wall carbon nanotube-polymer composite

We present a detailed investigation of pulse width and spectral dynamics of an Er-doped soliton fiber ring laser, mode-locked by a carbon-nanotube-polymer composite. The laser is stable and produces ∼ 650 fs pulses at a fundamental repetition rate of 20.8MHz. The carbon nanotube saturable absorber has a low saturation intensity of ∼ 18.9 MW/cm and a 16.9% reduction in absorption (due to saturat...

Transform-limited pulse generation in normal cavity dispersion erbium doped single-walled carbon nanotubes mode-locked fiber ring laser.

We demonstrate an erbium doped fiber ring laser mode-locked with a carboxymetylcellulose high-optical quality film with dispersed single-walled carbon nanotubes (SWCNT). The laser with large normal net cavity dispersion generates near bandwidth-limited picosecond inverse modified soliton pulses at 1.56 µm.

1700 nm dispersion managed mode-locked bismuth fiber laser

We demonstrate the first 1.7 μm bismuth-doped fiber laser generating ultrashort pulses via passive mode-locking. Pulse operation has been achieved for both anomalous and normal dispersion of the laser cavity owing to broadband characteristics of carbon nanotube saturable absorber. The laser delivered 1.65 ps pulses in net anomalous dispersion regime. In normal dispersion regime, the laser deliv...

Laser dynamics and relative timing jitter analysis of passively synchronized Er- and Yb-doped mode-locked fiber lasers

Passively synchronized Er-doped and Yb-doped mode-locked fiber lasers with a master–slave configuration are theoretically investigated based on the pulse propagationmodel for simulating pulse collision in the common fiber section and on the master equation model for simulating laser dynamics. Computational results indicate that the central optical frequency of the slave Er laser will be shifted...
