Abstract
We show that the Fabry-P´erot cavity dynamics of quantum cascade lasers (QCLs) play an important role in the gain recovery observed in a pump-probe experiment. Due to the residual pump power in the cavity after the pump pulse is reflected from the facet, the probed gain recovers at a slower rate.
