We built a set of four-outputs Nd∶glass pump source system with stable energy output, uniform spot and time-domain approximate square waveform. The system can achieve output of 4×180 J at 1053 nm in fundamental frequency and 4×80 J at 526.5 nm in double frequency. The main structure consists of 4 parts, which are the front-end seed source, the regenerative amplifier, Nd∶glass rod amplifier chain and the KDP frequency doubling crystal. Those two fundamental frequency beams with vertical polarization are combined by the polarizer. The 526.5 nm double frequency laser pulse with the same directivity and polarization is obtained after Type-Ⅱ phase matching frequency-doubling KDP crystal. As a result, the compact dual pulse pump source for the Ti∶sapphire amplifier is realized.
