A new type of doublecontrol AO driver has been developed. The doublecontrol driver can synchronously control the work time of both LD and the AO Qswitched, has over 10W output power and less than 15ns open-shutdown time. The new LD pumped AO Qswitched allsolidstate green laser applied this doublecontrol driver has much better performance in compare with the normal ones: saving electric power more than 50%, temperature rising at main parts of the laser set dropping down with more than 10℃, the time taken for thermally stable state being reduced to 22%. Pumped by a 1W LD, the output pulses with peak power of about 1kW and width of 14.5ns are obtained.
