Recent advances in optical refrigeration of a load (Conference Presentation)

Paper Abstract

Laser cooling of solids has advanced immensely in recent years and temperatures well below 100 K have been demonstrated in Yb:YLF crystals. We will discuss our progress towards developing a functional all-solid-state cryocooler based on this principle. We present data and analysis concerning laser coupling efficiency, thermal link between the cooling crystal and the cold-finger, shielding the load from the fluorescence, and overall thermal load management. Considerations for building a cooler prototype for specific applications will also be discussed.
