摘要：
Based on the propagation law of the cross-spectral density function, a closed-form expression for the spectrum of polychromatic Gaussian beams propagating through ail astigmatic aperture lens is derived., and some special cases are discussed. Numerical calculation results are given to illustrate how the astigmatism affects the behavior of spectral switches. (C) 2004 Elsevier B.V. All rights reserved.
