We present a theoretical study on the recombination of a free electron intothe ground state of a hydrogen-like ion in the presence of an external laserfield. Emphasis is placed on the effects caused by the laser dressing of theresidual ionic bound state. To investigate how this dressing affects the totaland angle-differential cross section of laser assisted radiative recombination(LARR) we apply first-order perturbation theory and the separableCoulomb-Volkov-continuum ansatz. Using this approach detailed calculations wereperformed for low-$Z$ hydrogen like ions and laser intensities in the rangefrom $I_L=10^{11}\text{W/cm}^2$ to $I_L=10^{13}\text{W/cm}^2$. It is seen thatthe total cross section as a function of the laser intensity is remarkablyaffected by the bound state dressing. Moreover the laser dressing becomesmanifest as asymmetries in the angular distribution and the (energy) spectrumof the emitted recombination photons.
