【Abstract】 The paper introduces a new method for measuring the radial intensity distribu-tion and the diameter of the Gaussian beam. The radial intensity distribution and the diameter of the Gaussian beam can be obtained by measuring only the intensities on three coordinate point in the same cross section of the Gaussian beam.更多还原
