【Abstract】 A measuring method for the diver（?）nce of single-mode TEM₀₀ laser Gaussian beam by gratings with different Q values is developed.Based on the theoretical computation and the error analysis for one dimensionality regression equations,linear relations which can be applied to measuremen and a number of theoretical errors less than 1% are derived.更多还原
