Abstract

Moderate feedback levels in edge emitting semiconductor lasers may cause different unstable regimes of operation. One of them is known as the regime of Low Frequency Fluctuations. We performed an experimental study of this regime on a picosecond time scale using a single-shot streak camera. Our measurements show the fine temporal structure of the laser emission in this regime and reveal the multimode nature of laser operation.
