A comprehensive theoretical approach to describe the electron-ion radiative recombination in the presence of intense, short laser pulses, which accounts for nondipole corrections is presented. It is based on the relativistic Coulomb-Volkov solution describing an electron in a combined Coulomb potential and a laser field, which is systematically expanded in powers of 1/c. Thus, it allows us to trace the origin of nondipole effects observed in the spectrum of emitted radiation. Hence, as we demonstrate for high-frequency pulses assisting the process, a significant extension of the cutoff and asymmetry in angular distributions of the emitted radiation can be attributed to the electron recoil off the laser pulse. In addition, we investigate a possibility of enhancing the efficiency of the generated high-energy radiation by chirping the pulse.
