| 英文摘要 | PURPOSE:To suppress the output change and to stabilize the recording action by forming the optical recording media side output edge surface by inclining in to the light axis and forming the reflecting edge surface of the semiconductor laser opposite to the output edge surface vertically to the light axis. CONSTITUTION:For the formation of the edge surface of the semiconductor laser, to constitute the laser resonator, a light axis 31 of the semiconductor laser arranges a reflecting edge surface 33 at an angle B diagonal to the reflecting surface of optical recording media 21 and the light axis 31 is made vertical to the optical recording media 21 and the reflecting edge surface 33. Namely, the light axis is inclined in the thickness direction of a semiconductor laser 14. In case of the semiconductor laser 14 provided on a heat sink 34, at an output edge surface 32, the laser light is almost refracted, comes out into an air 35 and reflected on the optical recording media surface, and thereafter, a light R1 to return into the activated layer is specially minimized. Thus, the modulating degree of the light strength due to the interference with a reflecting light R2 from the optical recording media 21 is significantly reduced. |
