In a preferred embodiment of a light source unit accord-ing to the invention, the deflecting unit is designed as a variable diffraction grating for decomposing the ini-tial pump light beam into partial pump light beams de-flected according to different diffraction orders. The partial pump light beams exit the grating at a respective diffraction angle each, the corresponding angular distribution being dependent on the grating structure. Here, the variation of the angular distribution of the de-flected pump light can, for example, be performed by me-chanically exchanging the grating in a revolver.
