Paper Abstract

We discuss recent progress in the laser cooling experiments via resonant cavity. Following analysis of the cooling efficiency, we highlight importance of wavelength dependence of the minimum achievable temperature for a given cryocooler. Following the analysis, we utilize pump detuning along with reduction of thermal load on the sample to achieve absolute temperature of nearly 200K, a 98.5 degree drop, starting from room temperature. Wavelength dependent analysis suggests that further improvement is possible.
