The present invention provides a spectral beam combined laser system comprising an optical gain element array, a transform element, a diffraction element and a reflecting element, which are sequentially positioned in an optical path, wherein said optical gain element array comprises a plurality of gain elements radiate laser beams having different wavelength; said transform element focuses and spatially overlaps the laser beams received from said optical gain element array at said diffraction element; said diffraction element diffracts the laser beams spatially overlapped by the transform element to the reflecting element; and said reflecting element feeds back a portion of the laser beams to the optical gain element array in a V-shaped off-axis external cavity with off-axis angle, wherein said V-shaped off-axis external cavity is formed between the reflecting element and the optical gain element array.
