Abstract

An optical fiber includes a first optical fiber body, a second optical fiber body and a first end cap. The first optical fiber body includes a first core and a first cladding. The second optical fiber body includes a second core and a second cladding, and is joined at a first end surface thereof to a first end surface of the first optical fiber body. The first end cap has light permeability and is joined to a second end surface of the second optical fiber body. The first core is doped with a laser medium. A mass content of the laser medium in the second core is lower than that of the laser medium in the first core.
