Abstract

In this paper, the theories of CW- laser and pulse laser were analyzed. A novel wide pulse laser is provided. Its pulse width is 1-6ms , the wave length is 1.064 µ m, the energy is 2-6 J. Using high repetition frequency electro-optical Q-switching at a repetition of 1000-5000Hz, it can obtain a series ofshort pulse, whose width is 30-50ns. The pumping of power of the wide pulse laser is decided by IV ? t, where the ? t is the width of electric —pulse. By adjusting ? t, the output power and pulse width can be adjusted . The wide pulse laser can be widely used for machining and therapy.
