Extensions of the SHG process are third-harmonic generation (THG), where the wavelength at one-third the incoming wavelength is created by the interaction
of an SHG beam with its fundamental; and fourth-harmonic generation (FHG), where the SHG beam is frequency-doubled again. All…

…fluorophores
like NADH typically require excitation at
710-800 nm. This leaves SHG and THG as
potential candidates for preclinical and
clinical purposes.
As their names indicate, in SHG and THG,
a fraction of incident
laser light is coherently converted to the
