SHG from collagen. (a) Forward and backward SHG emission from radiating dipoles (collagen fibers) oriented parallel and perpendicular to the laser propagation. (b) Excitation and emission of a single collagen fiber. (c) Collagen fiber orientation with respect to laser polarization gives rise to either zero, strong, or weak SHG signal. Reproduced from Ref.
