光束

Methods According to the document of ISO/TC172/GW1 N80 about the test principle and the experimental demands of times-diffraction-imit factor M^2, beam diameters in different z places along the light direction were measured using LBA-300PC laser beam quality analyzing meter made in Spiricon Corporation of America. Hyperbolas were fitted utilizing the measured data.
