Abstract

This paper studies the spectral beam combining technology for multiple Main Oscillation Power Amplifier（MOPA） pulse lasers by using the array fiber grating spectral beam combining technology.Then it simulates the output process of the multiple MOPA pulse laser by using this technology and studies the distortion of the time domain pulse shape after beam combining and presents the method for improving the output pulse flattening.The study results indicate that the output pulses become more flattened by controlling the synchronization of the input MOPA pulse laser in each channel with an interval of 2 ns.
