We propose a novel Arrayed Fiber Grating(AFG)-based spectral beam combining configuration
which is characteristic of good single-mode properties of output light spots
combined with high system reliability and scalability.Simulation results from Gaussian approximation indicate that this configuration has high diffraction efficiency
small output light spot size and good single-mode characteristics.
