The feasibility study of beam propagation ratio (M2) measurement made by the two-point knife-edge method
碩士 === 輔仁大學 === 物理學系碩士班 === 101 === Abstract The beam propagation ratio (or the beam quality factor, or the times-diffraction-limit number), M2, is the most fundamental parameter to describe the propagation of laser beams and their ability to be tightly focused. M2 is based on the second moments of...
