The paper reports the pregress in our six beam subnanosecond Nd-glass high power laser facility. Now the improved laser system is able to generate pulses with the following parameters: Pulse width can be selected from four ranges: 100 ps, 250 ps, 400 ps and 1ns; Pulse shape is controllable basically either in smooth mode or in modulated mode; Spectrum width is tunable in the ranges of ≤1A and 20～30A; Output energy can be also chosen in the way that for single beam it is 5～10 joules with pulse width of 250 ps and is 10~15 joules with pulse width about 1 ns. The experimental data of long period operaiion stability are given in the end part of the paper.
