Abstract
A feature of a wavelength conversion device of this invention is the board range of selection of wavelengths which can be obtained by conversion. A wavelength conversion device of this invention comprises an SC light generation portion, which receives an excitation light pulse output from an excitation light pulse source and generates SC light, and an optical wavelength filterwhich filters the SC light. An excitation light pulse source generates an excitation light pulse, of central wavelength λ. When the excitation light pulse generated by the excitation light pulse source is incident on the SC medium, SC light having a flat spectral shape over the range from wavelength λto wavelength λ(where λ<λ) is generated. The optical wavelength filter has a characteristic such that the filtering transmitted central wavelengths are λ, λ, λ, . . . , λ(where n is a natural number). A further feature is that the following conditions (1) and (2-1), (2-2), . . . , (2-n) between the wavelength λ, the wavelength λ, the wavelength λ, and the wavelengths λ, λ, λ, . . . , λ(where n is a natural number) are satisfied.λ<λ<λ  (1)λ<λ<λ  (2-1)•••λ<λ<λ  (2-n)
