Abstract

In this work, by using 4x4 ray-pulse matrices, we analyze the influence of the position of the output diffraction grating in 4f- and 2f-2f-systems with respect to the eventually introduced group-delay dispersion, spatial and angular chirp. We show that in the 4f-configuration, in contrast to the 2f-2f-setup, the grating offset does not cause angular chirp and pulse front tilt. We theoretically derive an expression for the interferometric autocorrelation signal in the presence of an arbitrary pulse-front tilt.
