摘要：
With the optimized side pumped module structure, three laser diode arrays rotating symmetrically pump the Nd: Glass rod. The size of the Nd: Glass rod is Phi 2 mmx75mm, with the doping concentration of 4a%. The surface of both ends of the rod coated with antireflection film at 1053nm, the rod was tilted 1.5 degrees in order to eliminate the oscillation of amplified spontaneous emission (ASE). The seed, with energy 10 mu J, operating frequency of 1Hz, pulse width 3ns, output wavelength 1053nm, through the Nd: Glass amplifiers reaches 70 times stable high-gain when the pumping power is 8.2kW and the pulse-width is 400 mu s. Meanwhile, the fluorescence distribution of the amplifier is homogeneous.
