PURPOSE: A dual optical fiber multiplets is provided to obtain a uniform laser pumping light source through spatial combination of temporal and spatial variation of the light source with an optical fiber length. CONSTITUTION: According to the dual optical fiber multiplets, temporal pulse width and spatial amplitude of two beams are changed by adding laser pulses of the two beams temporarily and spatially using two optical fibers with different length each other. And two optical fibers are combined to add the laser pulses of two beams temporarily and spatially using the optical fibers.
