摘要：
In this paper, an all-fiberized transverse mode-switching method was proposed based on temperature control of few-mode (FM) fiber Bragg gratings (FBGs). Two types of fibers were selected to fabricate the FBG pair in order to match the reflection peaks of the desired mode. The temperature-dependence property of the FM FBGs has been utilized to tune the reflection spectra. Through temperature control, 20 W level output power was obtained when the output laser was switched between the LP11 mode and the LP01 mode in both an all-fiberized ytterbium-doped laser and a Raman laser, which is increased by similar to 2 orders of magnitude compared with previous demonstrations (almost less than 100 mW).
