【Abstract】 In this paper, the mechanism of CWlaser and pulse laser are analyzed. A novel wide pulse laser is provided whose pulse width is 1～6ms, with the wave length of 1.064μm, and the output energy of 2～6J. Using high repetition frequency electrooptical Qswitching at a repetition of 1～5kHz, a series of short pulse can be obtained, whose width is 30～50ns. The pumping power of the wide pulse laser is dependent on IVΔt, where Δt is the width of electricpulse. By modifying Δt, the output power and pulse width can be adjusted.更多还原
