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.
