Optics at the service of nanotechnology, biomedical procedures and ultra-efficient solar power generation Jeffrey Gordon Ben-Gurion University of the Negev Department of Solar Energy & Environmental Physics Jacob Blaustein Institutes for Desert Research Recent advances in optical design have created new possibilities in a number of diverse cross-disciplinary areas. This lecture will survey novel progress in (1) new high-temperature reactors for the synthesis of inorganic nanomaterials that represent fundamentally new molecular structures, (2) light-based medical surgery, and (3) the generation of electricity from sunlight at unprecedented efficiencies. The design principles are rooted in non-imaging optics, for radiative transfer at the thermodynamic limit, especially germane when image fidelity is immaterial but reconstituting the immense irradiance of ultra-bright light sources is paramount. Experimental results that verify these newfound capabilities are presented for each application.
