Latest Patents

One of Buchwald's latest patents is titled "Optical refrigerator using reflectivity-tuned dielectric mirrors." This invention describes a method where selected working materials can be optically pumped using monochromatic radiation. The resulting fluorescence has an average photon energy that is higher than that of the pumping radiation, leading to net anti-Stokes fluorescence. By employing parallel mirrored faces, the optical path of the incident pumping radiation is increased through multiple reflections within the working material. The use of reflectivity-tuned dielectric mirrors enhances the efficiency of the optical refrigerator by allowing higher-energy fluorescence photons to escape while trapping lower-energy photons. This innovative design can take the form of a disk with a large diameter and small height or a cubic shape with tuned mirrors on multiple sides. Additionally, photocells can be integrated to convert escaping fluorescence energy into electricity, further improving the system's efficiency.
