半導体レーザ結合器。 Semiconductor laser, 1 or 2 for efficiently coupling the output beam of the semiconductor laser to an optical fiber
In a semiconductor laser coupler consisting of a coupler lenses and an optical fiber whose input end is processed obliquely to the optical axis, the coupling occurs due to positional deviation between the semiconductor laser and the coupler lens in a plane perpendicular to the optical axis. With respect to the laser beam emitted from the lens at an angle determined by the amount of positional deviation with respect to the optical axis, the diagonal direction of the optical fiber is formed by the optical axis and the laser beam emitted from the coupling lens. A semiconductor laser coupler characterized by being installed perpendicular to and facing outward.
