Abstract
Using transient four-wave mixing spectroscopy, we study the ultrafast nonlinear optical response of magnetoexcitons in GaAs at 1.6 K. By spe ctrally and temporally resolving the coherent emission, we measure the magnetic field dependence of Coulomb interactions between magnetoexci tons. Contrary to experiments performed in quantum wells, these intera ctions persist for field strengths up to 10 T.
