Abstract
(EN)
A dual laser output device having optimized laser coupling efficiency of the present invention comprises: a first oscillator which outputs a laser of a first wavelength; a second oscillator which outputs a laser of a second wavelength; a fiber coupler that makes a predetermined laser incident on an input point incident to an optical fiber; and a laser selection part having a beam selection mirror which is configured to block the laser of the first wavelength and guide the laser of the second wavelength to the fiber coupler by being placed on a first optical path through which the laser of the first wavelength reaches the input point of the fiber coupler, and to guide the laser of the first wavelength to the fiber coupler by being removed from the first optical path.
