  We analyze theoretically optical generation of a spin-polarized charge
current (photogalvanic effect) and spin polarization in graphene with Rashba
spin-orbit coupling. An external magnetic field is applied in the graphene
plane, which plays a crucial role in the mechanism of current generation. We
predict a highly efficient resonant-like photogalvanic effect in a narrow
frequency range which is determined by the magnetic field. A relatively less
efficient photogalvanic effect appears in a broader frequency range, determined
by the electron concentration and spin-orbit coupling strength.
