Fourth Harmonic Generation
Request for Quotation >Fourth Harmonic Generation (FHG) is a process whereby light is generated at a wavelength which is 1/4 of the pump wavelength, and it occurs through a two stage nonlinear interaction. The first interaction is doubling of the pumping laser, followed by the further SHG of the generated wavelength.
Raicol Crystals provides the following types of crystals for FHG applications:
