Abstract

Provided is an optical processing device including: a beam emission portion which includes a plurality of optical fibers; a dispersion element which disperses a beam emitted from one optical fiber of the plurality of optical fibers; a condenser lens which focuses the beam passing through the dispersion element; an optical path conversion optical system which converts an optical path of the beam passing through the condenser lens so that the beam is incident to one of the other optical fiber of the plurality of optical fibers; and an optical path length adjustment portion which adjusts an optical path length of the beam incident from the optical path conversion optical system to said one of the other optical fiber. The optical path conversion optical system includes a mirror element which reflects the beam at a first reflection point and an intermediate mirror which reflects the beam reflected from the mirror element at an intermediate reflection point. The mirror element reflects the beam reflected from the intermediate mirror at a second reflection point. The condenser lens forms a focus of the beam at the first refection point. The optical path length adjustment portion has a refractive index higher than that of air, and the beam is able to be transmitted therethrough.
