A multiple wavelength laser light source using a fluorescent fiber includes a blue semiconductor laser element ( 2 ) for emitting an excitation light (a), and an optical fiber ( 17 ) having a first side fiber end face and a second side fiber face, the excitation light (a) from the blue semiconductor laser element ( 2 ) being made incident to the first side fiber end face, the excitation light (a) thus made incident to the first side fiber end face being emitted through the second side fiber face, in which the optical fiber ( 17 ) has dichroic mirror portions constituting a laser resonator ( 3 ) in its first and second side fiber end faces, respectively, and a core of the optical fiber ( 17 ) is made of a wavelength-converting member including a low phonon glass containing therein at least praseodymium ions as trivalent rare earth ions for emitting wavelength conversion lights by being excited by the excitation light (a).
