Abstract

Gain-switching of semiconductor lasers is an established technique to generate short optical pulses. For many applications of these lasers and for further pulse compression it is of large importance to know the dynamic of the spectral behavior. Recently, time-resolved spectra of GaAs/GaAlAs semiconductor lasers emitting around 850 nm have been discussed.^1,2 We have performed investigations of the spectral dynamics on semiconductor lasers with an emission wavelength of 1,3 μm, and have estimated the gain under the conditions of strongly gain-saturated emission.
