摘要：

We are currently developing a large aperture neodymium-glass based high-power solid state laser, Shenguang-III (SG-III), which will be used to provide extreme conditions for high-energy-density physical experiments in China. As a baseline design, SG-III will be composed of 48 beams arranged in 6 bundles with each beam aperture of 40cmx40cm. A prototype of SG-III (TIL-Technical Integration experimental Line) was developed from 2000, and completed in 2007. TIL is composed of 8 beams (four in vertical and two in horizontal), with each square aperture of 30cmx30cm. After frequency tripling, TIL has delivered about 10kJ in 0.351 mu m at 1 ns pulsewidth. As an operational laser facility, TIL has a beam divergence of 70 mu rad (focus length of 2.2m, i.e., 30DL) and pointing accuracy of 30 mu m (RMS), and meets the requirements of physical experiments.
