Mode Coherence Coefficients and Mode Decomposition Theory of Flattened Gaussian Beams

Zhang Bin Lü Baida Luo Shirong (Institute of Laser Physics & Chemistry, Sichuan University, Chengdu 610064) (Received 9 September 1998; revised 13 October 1998)  
By using the theory of partially coherent light, the analytical expression for the mode coherence cofficients of flattened Gaussian beams has been derived in the cylindrical coordinate system. Furthermore, based on the generalized M 2 factor of laser beams which was derived by the authors, the mode decomposition theory of flattened Gaussian beams has been built up.
