摘要: A device and method for laser cooling of a solid to extremely low temperature is disclosed, the including an active structure having high purity surface passivated direct band gap semiconductor crystal less than about 3 microns thick transparent hemispherical body in optical contact with crystal. The itself cooled when illuminated beam tuned frequency no greater edge Cooling caused by emission photons higher energy entering crystal, additional being accounted process absorption thermal phonons from lattice.
