Laser light source and manufacturing method therefor |
摘要 |
In a method of manufacturing a laser light source according to the present invention, an optical fiber having a diffraction grating is produced in which a plurality of refractive index changing portions are formed along the direction of an optical axis of the optical fiber. Then, the optical fiber having the diffraction grating is inserted into a ferrule, the optical fiber is bonded thereat, and the end surface of the ferrule is ground. Further, a laser oscillating device is prepared, and the laser oscillating device is coupled with the optical fiber having the diffraction grating and being inserted in the ferrule. <IMAGE> |
