چکیده انگلیسی
Aiming at the problem that the channel number in spectral beam combining (SBC) of fiber lasers array is limited by the narrow spectral selectivity of grating, a new scheme based on cascaded volume Bragg gratings (VBG) is proposed to expand the channel number. A system cascaded by two VBGs is presented and analyzed. A formula used to accurately determine the angle of incidence of all the channels is derived using rigorous coupled-wave analysis (RCWA). The channel number can be multiplied with increasing the number of VBGs. Numerical results show that the system based on cascaded VBGs is a good SBC combiner that has the ability to combine a large number of channels.
