Progress in China's six beam subnanosecond Nd-glass laser facility

The paper reports the progress in a six beam subnanosecond Nd-glass high power laser facility. At present the improved laser system is capable of generating pulses with the following parameters: Selectable pulse width in four ranges: 100 ps, 250 ps, 400 ps, and 1 ns, controllable pulse shape either in smooth mode or in modulated mode, tunable spectral width in the range from below 1 A to 20-30 A, output energy selectable for a single beam, 5-10 joules for pulse width of 250 ps, and 10-15 joules for pulse width about 1 ns. The experimental data on long term operating stability are also given.
