Abstract
We present a brief analysis of laser cooling in semiconductor quantum wells with emphasis on a previous experiment that gave evidence for local cooling. This work is re-examined in the context of light management, heat removal, and how increasing photo-carrier density affects luminescence. Our main conclusion is that using a single laser to both pump the sample and monitor temperature may lead to ambiguity in semiconductor cooling experiments.
