摘要

We present a detailed investigation of pulse width and spectral dynamics of an Er3+-doped soliton fiber ring laser, mode-locked by a carbon-nanotube-polymer composite. The laser is stable and produces similar to 650 fs pulses at a fundamental repetition rate of 20.8 MHz. The carbon nanotube saturable absorber has a low saturation intensity of similar to 18.9 MW/cm(2) and a 16.9% reduction in ab-sorption (due to saturation) at high pulse intensity (similar to 270 MW/cm(2)). Spectral and transient effects confirm the soliton operation of the laser. (C) 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
