dc.description.abstract© 2015 Elsevier Ltd. All rights reserved.We present a detailed analysis of a nanosecond-pulse single-walled carbon nanotube (SWCNT) passively mode-locked O-band Raman fiber lasers. As gain medium, single mode fiber (SMF) and highly nonlinear Raman gain were used at three different experimental setups. By incorporating 1.0 nm mean diameter SWCNT as saturable absorbers (SA) at 2.3 km SMF long-length gain medium setup, soliton-like spectrum followed by nanosecond high chirped pulse was observed at cavity fundamental repetition rate. In order to shorter the chirped pulse, intracavity anomalous dispersion was introduced with normal dispersion shift fiber (DSF) lengths and pulse duration decreased from 4.20 to 2.30 ns. By using highly nonlinear Raman gain medium in the O-band Raman laser configuration, the laser generated clean and well-defined nanosecond high chirped pulses, achieving pulse duration as short as 2.30 ns with 230 m gain medium length. Also, we could estimate the picosecond pulse duration region as a function of gain medium length of this laser and compared with SMF pulse shortening curve. As results, the lasers presented similar tendencies, indicating a strong influence of nonlinearities and dispersion in the pulse duration shortening.
