英文摘要	PURPOSE:To obtain a light source hardly generating aberration by fixing a single mode fiber at a light emitting spot in the upper edge face of a laser chip and extracting circular outgoing beams through the single mode fiber. CONSTITUTION:A single mode fiber 11 mounted at a light-emitting spot in the upper edge face of a laser chip 3 is fastened to the chip 3 with a resin 12. The core diameter of the fiber 11 is conformed to the light-emitting spot in the upper edge face of the chip 3 and the resin 12 is used on the fixation. The bond area of the fiber 11 is AR-coated previously, thus inhibiting reflection on bond. Since a beam diameter generally extends over 2-3mum and the core diameter of the fiber 11 extends over values such as 9-10mum, the chip 3 and the fiber 11 are brought near as much as possible and assembled, thus efficiently coupling beams. Accordingly, beams emitted from the fiber 11 are shaped, and formed to a circular shape, and the greater part of aberration are removed, thus acquiring ideal laser beams 4a.
