12. We have carefully checked that the Rayleigh scattering from the pump pulse negligibly interferes with the probe.
13. For comparison, it is worth noting that the probe coherent gain in free-space QW’s, estimated from Ref. 3, is of the order of (Formula presented) near the exciton energy, while spectral integration of the whole probe spectrum leads to a large net absorption.
