A new technique, multi-pulse modulation technique for generating short laser pulse is developed. Applying this technique to a electro-optics Q-switched Nd:YAG laser, completely modulated laser pulse trains can be obtained. The width of a single pulse in the trains is less than 1 ns, with peak power higher than 15 MW, and the amplitude stability of the pulse train is better than 5%.
