摘　　要：A laser-diode-pumped high-pulse-energy Nd：LiYF4 master oscillator power amplifier 1053 nm laser system is demonstrated. We design a home-made pump module to homogenize the pump intensity through the ray tracing method. To increase the extraction efficiency, the pre-amplifier adopts a double-pass amplification structure. At a repetition rate of 50 Hz, 655 mJ pulse energy and 12.9 ns pulse width of 1053 nm laser is obtained from the master oscillator power amplifier system. The corresponding peak power is 51 MW. The optical-to-optical efficiency of the system is about 9.7%.A laser-diode-pumped high-pulse-energy Nd：LiYF4 master oscillator power amplifier 1053 nm laser system is demonstrated.
