The experimental situation in which excitons in Cu2O are pumped directly into a state
with wave vector = k0 by two counter-propagating laser pulses, and subsequently probed by
a third, time-delayed, pulse has been theoretically investigated. It has been shown that
additional electromagnetic waves are excited in the system. A specific configuration of two
pump pulses and one probe pulse has been found to generate only one additional
electromagnetic wave. The dependence of the time-integrated photon number in this wave on
the delay time between pump and probe pulses for some values of the detuning has been
investigated.
