The cross-sections and polarization of the produced e(+/-) for the pro
cess gamma omega --> e(+)e(-), as well as the cross-sections of the pr
ocess gamma omega --> gamma gamma summed over the polarizations of fin
al particles are calculated for various polarizations of colliding hig
h-energy gamma-quanta (gamma) and laser photons (omega). The obtained
numerical results allow to discuss the feasibility of the experimental
investigation of these processes.
