摘　　要：A laser diode array side-pumped Nd：glass square rod amplifier of the dimensions 12 mm x 12 mm is designed. The fluorescence is evenly distributed in the Nd：glass amplifier. When the pump power is 66.32 kW, the small signal gain increases by 3.23 times. Under the condition of a 1 Hz repetition frequency, 50 mJ of injected seed- light energy, and a 10 mm × 10 mm aperture, the output energy of the laser beam can reach 1.62 J during the four-pass amplification. The output energy stability of the laser pulse is 2.94% （RMS）, and the square pulse distortion is smaller than 2. The energy amplification of the injected laser beam from millijoules to joules is realized.A laser diode array side-pumped Nd：glass square rod amplifier of the dimensions 12 mm x 12 mm is designed.
