Optical refrigeration of Yb:YLF crystals is used to cool an arbitrary payload (HgCdTe IR sensor) for the first time to below 135K in a completely vibration free environment. This milestone is made possible by the design and fabrication of a specialty thermal link that efficiently shields the payload from the intense fluorescence while sustaining frequent thermal cycling. We also show the latest advances in the design and implementation of novel thermal links that promise sub-100K payload temperatures. This investigation considers thermal link materials that are CTE-matched to YLF and includes rigorous optical and thermal modeling under various geometries.

Since optical refrigeration has been demonstrated in rare-earth doped media, its most logical application has been development of a radiation balanced laser (RBL). While efficient and versatile rare-earth solid state laser operates only on a few discrete wavelengths. At the same time semiconductor gain medium can be easily engineered to lase over the entire visible and near IR spectrum. But achieving cooling and RBL in semiconductor medium has proven elusive due to both fundamental (hard to simultaneously achieve gain and anti-Stokes luminescence) and practical (background absorption) reasons. Therefore, it would be worthwhile to consider an alternative, tandem structure in which rare earth doped medium would cool the optically pumped semiconductor laser. In this work we provide guidelines for development of such a laser and estimate its characteristics under realistic conditions.
