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…

The crystals in the THG and in the SHG are held at preset temperatures by ovens. The crystal in the SHG oven is sensitive to fast
changes in temperature because of the optical coatings on the
