摘要: Abstract An explicit expression is presented for the cross-spectral density function of light in any cross-section perpendicular to axis a beam generated by planar, steady-state, quasi-homogeneous source, whose intensity distribution and degree spatial coherence are both gaussian. The result used discuss some properties such beam. It found, particular, that ratio transvers (spatial) length width same every axis.
