Abstract
A fusion-bonded optical component is created using a laser oscillator for irradiating at least one beam of laser light upon optical components, for example an end of a rod lens and an end of an optical fiber. The optical components are fusion-bonded at respective ends. A CCD camera is used for observing a shape change caused by the laser beam irradiation of the ends during the fusion bonding, and a controlling section controls the laser oscillator to form a curved edge in the end portion, the controller controlling the irradiation of the rod lens and optical fiber based at least in part on the observation performed by the CCD camera.
