Abstract
A laser device that generates a CW laser beam in the ultraviolet range with a wavelength of less than 200 nm by inputting two laser beams having different wavelengths to a nonlinear optical crystal which is, for example, a CLBO crystal, to perform sum frequency mixing, and among the two laser beams, at least one laser beam is output from a fiber laser device. Thereby, the volume of the laser device portion of a processing device or a measuring device that uses an ultraviolet laser beam can be made small, and the effective use of workspace can be realized.
