| 英文摘要 | A light coupler is disclosed for use in transforming a flat cross-sectional output beam of a laser into a light beam having a substantially circular cross-section of a spot size for efficient coupling to an optical fiber. The light coupler includes first and second light transmission bodies disposed in an optically coaxial cascade relationship. The first and second light transmission bodies satisfy the conditions a.sub.x > a.sub.y (where a.sub.y can be zero) and a.sub.x .ltoreq. a.sub.y (where a.sub.x can be zero), respectively, the symbols a.sub.x and a .sub.y being the focusing parameters representing the values of change in the refractive index distribution in the x- and y-directions parallel to the thickness and width directions in the cross-section of the laser beam incident upon the light transmission bodies, in a plane normal to the optical axes of the light transmission bodies. |
