The condition of spectral invariance propagation of the spatially completely coherent light sources is studied from the diffraction theory. It is found that if the field distribution of light sources depends on frequency only through the variable (√kx,√ky), the spectrum of light will remain invariant on propagation. This scaling law may be generalized to the stationary light sources. But it can be destroyed by aperture. The spectral shifts of few cycle ultrashort pulses from aperture diffraction and a laser resonator with hard aperture are found and analyzed in detail.
In this paper, we derived an analytical solution of the pulsed beam propagating in second-order dispersive medium in the space-time domain, and then analyzed the space-time coupling of the pulse on propagation in medium.
