Figure 2
Set of PR-SHG images of a cPAH crystal conglomerate. Each image represents a unique combination of input and detected polarization. Row I corresponds to vertically polarized light at the detector and row II corresponds to horizontally polarized light at the detector. The respective input polarization for each image is given in the bottom left-hand corner of each SHG image (H, horizontally polarized; V, vertically polarized; + 45°, linearly polarized at + 45°; -45°, linearly polarized at -45°; RC, right-circularly polarized; LC, left-circularly polarized).  [article HTML]
