| 英文摘要 | PURPOSE:To automatically regulate a collimation stably by reflecting part of a light from a collimator lens on a flat reflecting surface, and returning it through a collimator lens having a chromatic aberration to a semiconductor laser. CONSTITUTION:A predetermined amount of chromatic aberration is provided in a collimator lens 2a instead of an objective lens in a self-focusing phenomenon, and a light is returned to a semiconductor laser 1 by a flat reflecting surface 8 instead of an optical disk in the phenomenon. Since the lens 2a has the chromatic aberration, a variation in a wavelength becomes that in a focal distance, and a predetermined amount of the returning light to the laser 1 is obtained by the surface 8 at this time. Thus, the regulation of the collimation is automated in a stable state without influence of the variation in the reflecting state of an object to which the light from the laser 1 is radiated. |
