“…The all-solid-state laser, which is featured by its small volume, high electro-optic conversion efficiency, simple structure, low cost and being made from all-solid-state devices of small volume, grows fast owing to the popularization of the laser diode array (LDA) with a wide application prospect in the space communication, coherent radar, medicine, micro processing, digital optical storage and high-power laser facilities [1][2][3][4][5][6][7][8] . Meanwhile, as the narrowband pulse has many problems in remission of B integral constraint and inhibition of the Stimulated Brillouin Scattering (SBS) effect on the transverse of the large aperture optical component.…”

A high beam quality and high stability laser amplifier baseing on LDA side-pumping Nd-Glass which applied to amplify a nanosecond laser pulse source has been developed in the paper. In addition, Liquid crystal spatial light modulator is used in the amplifier for spatial beam shaping so as to improve the near-field uniformity. When the flat top pules with the pulse width of 3ns and energy of 500nJ are injected as the seed pulse, the average output energy of the laser amplifier is 100mJ. The modulation degree near field is less than 1.22:1, and the beam angle drifting of the far-field laser is less than 10 μrad.

“…With features of small volume, high electro-optic conversion efficiency, simple structure, low cost and the feature that it can be made of all-solid-state devices of small volume, LDA has a broad application prospect in the laser device field [1][2][3]. On the other hand, as the narrowband pulse has many problems in remission of B integral constraint and inhibition of the Stimulated Brillouin Scattering (SBS) effect on the transverse of the large aperture optical component [4][5][6].…”

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 Φ2 mm×75mm, with the doping concentration of 4at%. The surface of both ends of the rod coated with antireflection film at 1053nm, the rod was tilted 1.5°in order to eliminate the oscillation of amplified spontaneous emission (ASE). The seed, with energy 10μJ, 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 400μs. Meanwhile, the fluorescence distribution of the amplifier is homogeneous.
