The Research of the Propagation and Focusing Properties of Gauss Beam with MATLAB
Abstract: Gauss beams and their propagation properties has formed a systematic theoretical system. It includes the basic properties of the Gauss beam, Gauss plex parameters and ABCD law, Gauss beam propagation, the transform of Gauss beams through a thin lens, the focusing properties of Gauss beams .According to the above theory, bined with the powerful numerical calculation and graphic MATLAB display function, complete the base mode Gauss beam propagating in free space and focusing characteristics simulation and gives the graphical display of the results, and deepen the understanding and application of the laser beam propagation and focusing properties.
