Recently, an optical dipole trap for atomic ions has been realized by our group. However, the reported lifetime of a few milliseconds is limited because of heating. Here we want to discuss cooling schemes for ions in optical dipole traps and report on first experimental data. Due to large Stark shifts and the requirements on the polarization of the dipole trap lasers, cooling mechanisms have to be modified in a way as to suit this new regime of optical trapping. Arising possibilities for new experiments at the border between atom and ion trapping are presented.
