Fig. 2From: Focusing characteristics of a 4 πparabolic mirror light-matter interfaceEffective excitation PSF in the xy (a), zy (b), and xz (c) plane when illuminating the full solid angle covered by the 4 π-PM. The corresponding line profiles through the center of the focus are shown in (d–f). They are overlayed to the line profiles resulting from numerical simulations (red)Back to article page
