    • Optical waveguides, lens arrays and laser collecting devices are disclosed. The optical waveguide is formed with an output surface which is made smaller in dimension in a fast axis direction than an input surface. The waveguide collects in the fast axis direction plural laser beams output from plural laser emitting parts arranged in the fast axis direction and outputs from the output surface. The entrance surface of the optical waveguide is provided with first lenses to correspond respectively to the plural laser emitting parts. Each of the first lenses is located to be offset first predetermined distances from a corresponding one of the laser emitting parts in the beam traveling direction and in said fast axis direction, and the first predetermined distances are determined for each of the first lens in taking into account the focal length of each first lens and an angle which each first lens makes with the output surface of the waveguide.
    • 公开了光波导,透镜阵列和激光收集装置。 光波导形成为具有比输入面在快轴方向尺寸更小的输出面。 波导从快轴方向收集多个从快轴方向排列的激光发射部输出的激光,并从输出面输出。 光波导的入射面设置有分别对应于多个激光发射部的第一透镜。 每个第一透镜被定位成在光束移动方向和所述快轴方向上偏离相应的一个激光发射部分的第一预定距离,并且对于每个第一透镜确定第一预定距离 考虑每个第一透镜的焦距和每个第一透镜与波导的输出表面形成的角度。

    • A fiber laser oscillator (1; 100) has an optical fiber (10), a pumping light emitting device (30), a light guide member (40; 140), and a core member (50). The core member (50) is configured to have a flat plate-shaped, cylindrical, annular, or hollow spherical configuration. The optical fiber (10) is wound around the surface of the core member (50) or partially embedded within the surface of the core member (50). The light guide member (40; 140) has a light receiving surface (40a) and an opposite surface (40b) opposing the receiving surface. The opposite surface (40b) of the light guide member (40; 140) contacts the circumferential surface of the core member (50). Light (Lin) emitted from the light emitting device (30) travels (i.e., pumping light (Lin)) travels within the core member (50) along the circumference of the core member (50) and excites the core portion (12) of the optical fiber (10).
