Abstract
A wavelength-converted light generating apparatusA includes: an excitation light sourcesupplying excitation light Lof a predetermined wavelength; and a wavelength conversion element, in which an aggregateof crystals of a dye molecule is held by a holding substrateand which, by incidence of the excitation light L, generates converted light Lthat has been wavelength-converted. The excitation light sourcesupplies the excitation light Lof a wavelength longer than an absorption edge of the dye molecule to the wavelength conversion element. The wavelength conversion element, by incidence of the excitation light Lon the crystal aggregate, generates and outputs the converted light (for example, visible light) Lthat has been wavelength-converted to a shorter wavelength than the excitation light (for example, near-infrared light) L. A wavelength-converted light generating apparatus and generating method capable of favorably generating light of a shorter wavelength than incident light of a predetermined wavelength by wavelength conversion is thus realized.
