  • Based on the fact that circ function can be expanded by an approximate sum of complex Gaussian functions with finite numbers,the analytical formula for the axial intensity distribution of a partially coherent Gaussian Schell model(GSM)beam through a circular lens with finite aperture was derived.The calculation was made and its results were compared to those of the diffracted integral.The result shows that our method can improve the calculation efficiency.

Abstract: Based on the fact that circ function can be expanded by an approximate sum of complex Gaussian functions with finite numbers,the analytical formula for the axial intensity distribution of a partially coherent Gaussian Schell model(GSM)beam through a circular lens with finite aperture was derived.The calculation was made and its results were compared to those of the diffracted integral.The result shows that our method can improve the calculation efficiency.
