Fabrication and characterization of a pulsed fiber ring laser based on As2S3

[摘要]：We demonstrate the operation of a fiber ring laser using a 19.5 cm segment of As2S3 chalcogenide fiber. The laser is passively mode-locked via nonlinear polarization rotation and provides two different operation regimes of picosecond and noiselike pulses. This ring configuration also enables an accurate measurement of the chromatic dispersion of the chalcogenide fiber. (C) 2012 Optical Society of America
