The structured beams, which can manipulate arbitrary intensity and phase of electromagnetic rays, are significant in communication and sensing. The vortex electromagnetic wave carrying orbital angu…
We examine how the introduction of monetary incentives by a knowledge-sharing platform affects the nonrewarded knowledge activity on the platform. Our setting is a question-and-answer platform that…
We present a novel structure of planar waveguide for Yb:YAG laser amplifiers as symmetrical corner-pumped planar waveguide, allowing large absorption length. We optimize the parameters of the waveg…
