Ultrafast stretched-pulse fiber laser mode-locked by carbon nanotubes

Abstract

Ultrafast fiber sources having short pulses, broad bandwidth, high energy, and low amplitude fluctuations have widespread applications. Stretched-pulse fiber lasers, incorporating segments of normal and anomalous dispersion fibers, are a preferred means to generate such pulses. We realize a stretched-pulse fiber laser based on a nanotube saturable absorber, with 113 fs pulses, 33.5 nm spectral width and ˜0.07% amplitude fluctuation, outperforming current nanotube-based designs.
