摘　　要：A new shaping method for producing nanosecond pulses with specific shape is introduced. When a Gaussian laser pulse passes through an electro-optic deflector, it. has been scanned as a line on the focal plane according to time precedence. Through controlling the intensity of transmitted light on each pixol of the liquid crystal spatial light modulator （LCSLM）, various complicated pulses can be easily produced. Using this method, various specific shaped pulses with pulse duration varying from 750 ps to 5 ns are achieved.A new shaping method for producing nanosecond pulses with specific shape is introduced.
