Multi-Fresnel-Lens Pumping Approach for Simultaneous Emission of Seven TEM00-Mo...
Costa, Hugo; Liang, Dawei; Matos, Ana; Almeida, Joana© 2024 by the authors. Licensee MDPI, Basel, Switzerland.; TEM00-mode operation is a requirement in many laser-based applications due to the small divergence and high-power density of the emitted laser beam. A solar laser scheme was designed and numerically studied with the goal of increasing the solar-to-laser power conversion efficiency in the TEM00-mode operation. The collection and primary concentration of ...
