Query: Enhanced photon emission from a double-layer target at moderate laser
  intensities   In this paper we study photon emission in the interaction of the laser beam
with an under-dense target and the attached reflecting plasma mirror. Photons
are emitted due to the inverse Compton scattering when accelerated electrons
interact with a reflected part of the laser pulse. The enhancement of photon
generation in this configuration lies in using the laser pulse with a steep
rising edge. Such a laser pulse can be obtained by the preceding interaction of
the incoming laser pulse with a thin solid-density foil. Using numerical
simulations we study the origin of such a laser pulse and its effect on photon
emission. As a result, accelerated electrons can interact directly with the
most intense part of the laser pulse that enhances photon emission. This
approach increases the number of created photons and improves photon beam
divergence.
