摘要	Rays of light emitted from the semiconductor laser are converted into parallel rays of light by cylindrical lenses. Then, the light passed through the cylindrical lenses is caused to enter an optical fiber changed continuously from a specific position in the middle toward an incidence end part in such a manner that the core shape at the incidence end part becomes elliptic, with the cross-sectional area remaining unchanged.
其他摘要	从半导体激光器发射的光通过柱面透镜转换成平行光线。然后，使通过柱面透镜的光进入从中间的特定位置朝向入射端部连续变化的光纤，使得入射端部的芯形变为椭圆形，并且交叉。截面积保持不变。
主权项	A laser apparatus comprising: a laser unit configured to emit laser light; an optical member configured to convert the laser light emitted from said laser unit into parallel light rays; and an optical fiber having a core with a predetermined cross-sectional shape, and being provided with a fiber end portion, said fiber end portion having an exterior side configured to receive the light rays from said optical member, and having an interior side being continued to the core of said optical fiber, the interior side of said fiber end portion being configured to have a given shape with a first area, the exterior side of said fiber end portion being configured to have substantially an elliptical shape with a second area of which amount is substantially equal to an amount of the first area of said interior side, and the given shape at the interior side of said fiber end portion changing continuously to the elliptical shape at the exterior side of said fiber end portion.
