Abstract
While a ferrule or a laser beam is being shifted in an axial direction, the laser beam is applied, thereby forming a plurality of welded portions at the boundary between a coating of an optical fiber and the ferrule. A YAG laser in a Q switch pulse mode is used to provide a laser beam. The beam. The YAG laser in the Q switch pulse mode is preferably oscillated in a pulse exciting system. The ferrule is made of transparent or semi-transparent synthetic resin. The coating of the optical fiber is made of translucent synthetic resin. In this way, an optical fiber fixing method can be provided which can surely fix an optical fiber and a ferrule in a shortened time, and minimize the thermal influence on the vicinity of the portion to be processed.
