A fiber laser and an optical device for controlling polarization and outputting single polarized light are provided in a simple structure. The fiber laser includes a solid-state laser fiber 3 doped with a rare earth element, a pump light source 1 for exciting the solid-state laser fiber, a reflective element 2 having wavelength dependency, and a wavelength conversion element 4 arranged at the output side of the solid-state laser fiber away from the reflective element at a specified distance along the solid-state laser fiber, in which an end face of the wavelength conversion element 4 is inclined to an optical axis.
