PROBLEM TO BE SOLVED: To attain a variable-wavelength light generator capable of outputting a laser beam with a wide variable wavelength range. SOLUTION: The variable-wavelength light generator is provided with: a first mixing means for mixing variable wavelength light which is short wavelength light with fixed wavelength light which is long wavelength light to output difference frequency light; and a second mixing means for mixing the difference frequency light to be output from the first mixing means with the variable wavelength light to output difference frequency light.
