The cooling rate for cavity-mediated laser cooling scales as the Lamb-Dicke parameter η squared. A proper analysis of the cooling process hence needs to take terms up to η2 in the system dynamics into account. In this paper, we present such an analysis for a standard scenario of cavity-mediated laser cooling with η≪1. Our results confirm that there are many similarities between ordinary and cavity-mediated laser cooling. However, for a weakly confined particle inside a strongly coupled cavity, which is the most interesting case for the cooling of molecules, numerical results indicate that more detailed calculations are needed to model the cooling process accurately.
