Abstract Optical refrigeration by fluorescence is a new concept in refrigeration that represents a revolutionary advance in small cryocoolers. It uses anti-Stokes fluorescence to remove heat from a glass or crystal that is pumped with laser light. We have completed a numerical model of the cooling process and designed an optical crycooler for a focal plane cooling application. Such a cryocooler appears feasible and has several advantages when compared to conventional devices, including small size, long life (no moving parts), zero vibration, low electromagnetic interference (EMI), and potentially low cost. Performance estimates of the device are presented based on the known performance of the cooling material and a detailed thermal model. The performance is compared to existing mechanical and thermoelectric coolers.
