Abstract
We investigate the resonant cooling phenomena of a driven two-level radiator embedded in a photonic-crystal structure. We find that cooling occurs even at laser-atom-frequency resonance. This happens due to atomic dressed-state coupling with different strengths, resulting in population redistribution and cooling. Furthermore, for off-resonant driving the two-level particle can be in either the ground or excited bare state. This may help in the engineering of different amplified optical devices as well as highly coherent light sources.
