Li Jia.Physical conditions for sources radiating a cosh-Gaussian model beam[J].Optoelectronics Letters,2011,7(4):308-312 Physical conditions for sources radiating a cosh-Gaussian model beam Author Name Affiliation Li Jia  Institute of Fiber Optic Communication and Information Engineering,College of Information Engineering,Zhejiang University of Technology；  Abstract:       Based on the coherence theory of diffracted optical field and the model for partially coherent beams,analytical expressions for the cross-spectral density and the irradiance spectral density in the far zone are derived,respectively.Utilizing the theoretical model of radiation from secondary planar sources,the physical conditions for sources generating a cosh-Gaussian(CHG) beam are investigated.Analytical results demonstrate that the parametric conditions strongly depend on the coherence property...
