Abstract
For the purpose of efficiently converting a beam profile of laser light with a simple configuration, provided is a beam profile converter including: a first optical fiber that outputs guided light from a first end surface; and a second optical fiber being a multi-mode optical fiber to which the light is input to a second end surface and configured to guide the light, in which a core diameter of the second optical fiber is larger than a core diameter of the first optical fiber at the first end surface, and the light output from the first end surface is input to a core portion of the second end surface at a position separated from an optical axis of the second optical fiber in a direction inclined with respect to the second end surface.
