Abstract
Official abstract text for this publication.
An optical fiber laser device includes optical reflectors making an invisible laser light from an amplification optical fiber; a light source outputting a visible light; an introduction unit outputting the laser light input to a first input terminal from a first output terminal mainly, outputting the visible light input to a second input terminal from the first output terminal mainly, inputting the visible light output by the light source connected to the second input terminal and introducing the visible light to the amplification optical fiber or a output optical fiber via the first output terminal; an optical multiplexer/demultiplexer outputting the visible light to the introduction unit, and outputting a leaking return light input from a side of the introduction unit; and a controller outputting the visible light from the output optical fiber in a case of determining a position at which the laser light will be irradiated.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical fiber laser device comprising: an amplification optical fiber; a pumping light source outputting a pumping light making the amplification optical fiber be subjected to optical pumping; optical reflectors being disposed at two sides of the amplification optical fiber and configuring an optical resonator making laser oscillation of an invisible laser light from a light generated in the amplification optical fiber; an output optical fiber guidi…
