Significance Heating is a major problem in semiconductor devices. Optical refrigerator using laser cooling will be free of vibration, mechanically robust and compact. It has far reaching implications in the area of optical detection systems and optoelectronic devices. Purpose invent a practical all-solid-state optical refrigerator to cool semiconductors using laser cooling. We hypothesize that laser cooling in semiconductors can achieve temperatures ~1 ...
