Goos–Hänchen and Imbert–Fedorov shifts for astigmatic Gaussian beams
In this work we investigate the role of the beam astigmatism in the Goos–Hänchen and Imbert–Fedorov shift. As a case study, we consider a Gaussian beam focused by an astigmatic lens and we calculate explicitly the corrections to the standard formulas for beam shifts due to the astigmatism induced by …
