Within the FAIR project, laser cooling of highly intense, ultra relativistic ion beams will be attempted for the first time, and in a large (circumference 1084 m) and strong (max. magnetic rigidity 100 Tm) synchrotron, called "SIS100". Laser cooling of such ion beams should result in a further increase of the longitudinal phase space density and in non-Gaussian longitudinal beam profiles. For stable operation of such ion beams, and for optimization of the cooling process, both the laser force and the high-intensity effects have to be studied numerically in advance. The efficiency of laser cooling has been analyzed for different synchrotron frequency regimes. At high beam intensities, intra-beam scattering and space-charge effects have been found to counteract the laser cooling force. We will discuss how they influence the laser cooling efficiency and thus affect the cooling time.
