  In this contribution we study for the first time the prompt photon production
in single and double diffractive processes considering the resolved Pomeron
model. We estimate the rapidity and transverse momentum dependence of the cross
section for the production of two photons and of a photon and a jet. We show
that these processes are sensitive to the pomeron structure. In contrast with
the dijet and heavy quark production, which are dominated by gluon-gluon
interactions, in prompt photon production, Compton like processes are dominant
for single photon plus jet events. This gives a unique oportunity to constrain
the quark distribution in the Pomeron. The results are obtained for the LHC
energy.
