  "abstract": "We report polarization- and angle-dependent lateral beam shifts observed at 458~nm upon reflection from a deep-ultraviolet (DUV) dichroic multilayer mirror. These Goos--Hänchen (GH) shifts originate from the phase of the complex Fresnel reflection coefficient and are quantitatively reproduced using a transfer-matrix model. Simultaneous reflectance (R), transmittance (T), and GH shift measurements provide complementary constraints on the coating's amplitude and phase response. The analysis is extended to transmission, predicting analogous phase-induced lateral shifts. In frequency-doubling cavities using dichroic mirrors, these phase effects can accumulate over multiple reflections, leading to deviations from ray-optics predictions that may affect cavity mode structure and resonance conditions. Our results show a GH shift of as much as 2~\\textmu m (\\bm{$\\approx 4.4λ$}), which, combined with RT data, enables improved characterization of the phase response of the multilayer coating. The p-polarized reflectance is minimized at a pseudo-Brewster angle of \\bm{$θ_B \\approx 46^\\circ$} at 458~nm, providing a natural reference point around which the GH shift is enhanced.",
