Abstract
We investigate the stimulated emission properties of an In0.18Ga0.82As /GaAs quantum-well microcavity laser under strong magnetic confinement . The dynamics depend sensitively on excitation intensity and cavity m ode energy, but show no magnetic-field dependence over a wide range of excitation conditions. The results evidence a fast relaxation which i s uninhibited by the quasi-three-dimensional quantum confinement, and may indicate an advantage in designing quantum dots with equidistant e nergy levels, where Coulomb scattering via an Anger process is expecte d to be highly efficient.
