Turn-on dynamics of semiconductor quantum dot lasers

We present a theoretical approach including Coulomb scattering to InAs/GaAs quantum dot lasers. In agreement with experiments we find strongly damped relaxation oscillations. We show the crucial importance of Coulomb interaction for this characteristic feature.
