Abstract
A multiwavelength comb is obtained from Er3+- and Nd3+-doped fiber lasers by incorporation of a section of multimode optical fiber into an otherwise single-mode fiber ring cavity. This combination of fiber types acts as a wavelength-dependent filter in the laser through spatial mode beating between the LP01 and LP11 modes in the multimode fiber.Keywords
