LIGHT SOURCE DEVICE, ANALYZER, AND LIGHT GENERATION METHOD

摘要

Wavelength conversion elements (130) are correspondingly provided to a plurality of laser light sources (110), and have different wavelength conversion characteristics to each other. Each wavelength conversion element (130) converts the wavelength of a laser beam incident on the wavelength conversion element. The wavelengths of the laser beams differ to each other after undergoing wavelength conversion. A multiplexer (150) combines a plurality of laser beams outputted from the plurality of wavelength conversion elements (130), and outputs the plurality of laser beams as coaxial light. A VBG (120) is disposed between the plurality of laser light sources (110) and the plurality of wavelength conversion elements (130), and constitutes at least part of a laser beam resonator.
