Abstract
"MetroLaser is proposing to perform a feasibility study of solid state optical cooling to very low (35 K) temperatures. Based on previously developed experimental and theoretical techniques, and a combination of a novel laser pumping scheme, recentdevelopments in materials processing, and a rigorous analysis of spectroscopic data at ultra-low temperatures, this study will result in a set of performance characteristics such as cooling efficiency, wall-plug efficiency, operating conditions, weight,size, cost, durability and operability. Using these results, a prototype design will be presented for a Phase II development. This study will focus on the effect of gravity on micro-crystal formation and the resulting optical properties at very lowtemperatures. However, it will also benefit the development of cooling devices aiming to work at 77 K operating temperature, which is a proven concept technology with benefiting features. These features include no moving parts, no electromagneticinterference, compactness, low weight, long operational lifetime, and relatively inexpensive manufacture. The potential to make inexpensive, efficient cooling devices that are driven by small powerful diode lasers may revolutionize satellite, computer, andhigh-temperature superconductor electronics industries. Optical solid-state cooling is a truly enabling technology, filling the gap between mechanical and thermo-electric cooling devices."
