摘要： A fiber laser with reduced stimulated Brillouin scattering includes a spool having a height and characterized by an induced temperature gradient with the height. The fiber laser also includes a fiber wrapped on the spool and characterized by a signal power increasing along the length of the fiber. The induced temperature gradient is a function of the signal power along the fiber.
