Abstract: Based on the laser beam classification in accordance with the spatial symmetry and spatial coherence,the parametric characterization of laser beams is studied.The anisotropic twisted Gaussion-Schell model (ATGSM) beam,isotropic twisted Gaussian-Schell model (ITGSM) beam,anisotropic Gaussian-Schell model (AGSM) beam,rotated astigmatic Gaussian-Schell model (RAGSM) beam,aligned astigmatic Gaussian-Schell model (AAGSM) beam,stigmatic Gaussian-Schell model (SGSM) beam,general astigmatic Gaussian (GAG) beam,rotated astigmatic Gaussian (RAG) beam,aligned astigmatic Gaussian (AAG) beam,and stigmatic Gaussian (SG) beam are taken as typical illustrative examples,their classification and the number of independent beam parameters are analyzed.Some related problems are also discussed.
