Paper Abstract

We present a study of non-resonant optical cavities for optical refrigerators. Designs have been studied to maximize pump light-trapping to improve absorption and thereby increase the efficiency of optical refrigeration. The approaches of non-resonant optical cavities by Herriott-cell and total-internal-reflection were studied. Ray-tracing simulations and experiments were performed to analyze and optimize the different light-trapping configurations. We present a trade-off analysis between performance, reliability, and manufacturability.
