Abstract
A semiconductor-fiber-laser assembly is provided that includes a pumping module, an active optical fiber and an assembling board. The active optical fiber is provided on an upper surface of the assembling board, the pumping module is provided on a surface of the assembling board that is the same as or opposite to the upper surface; and input-side and output-side optical-fiber gratings are provided at two ends of the active optical fiber, to form a laser resonator between the input-side and output-side optical-fiber gratings. The pumping module includes a plurality of semiconductor-laser single emitters, a collimating-lens group and a mirror group that are sequentially arranged, and light beams from the semiconductor-laser single emitters pass through the mirror group to realize beam combination.
