PURPOSE:To increase the output of an optical oscillator by a method wherein the end faces, in which light is introduced, on one side of a photoconductor are respectively formed into an inclined face or a curved face in such a way that virtual lines to pass through vertically to the end faces intersect an optical oscillation part and the end faces of a multitude of optical fibers are bonded vertically to the inclined faces or the curved faces with an optical paste or the like. CONSTITUTION:End faces 2b of a photoconductor 2 are respectively formed into an inclined face, vertical lines X-X to these inclined faces 2 are formed in such a way as to intersect an axial line O-O of an optical oscillation part 1 at the part 1 and the end faces of optical fibers 4 are bonded vertically to these inclined faces with an optical paste or the like. Similarly, inclined faces are respectively formed on the other end faces 2a as well of the conductor 2 and each reflection film 3 is formed on these inclined faces by depositing gold to contrive so as to introduce effectively lights as well reflected by the films 3 in the part 1. Moreover, the conductor 2 is formed not only the end faces 2a but also all its outer peripheral surfaces into a reflective surface 3' excepting the light introducing end parts 2b. Thereby, beams of light transmitted through the fibers 4 are fed more effectively to the part 1 and a strong laser beam can be generated. |
