Abstract
On the basis of the rate equation of laser oscillation, we study the capable of square wave output of solid state laser in temporal domain. By means of the smooth cavity dumping, the reduce of output loss compensated the photon decrease in cavity. In experiment, we use two sets of avalanche transistor chains to control the functional voltage which applied on the Pockels cell in order to get a uniform and pulsewidth variable square wave pulse laser. Compare with the traditional Gaussian pulse, the pulsewidth variable square wave laser pulse has some advantages in waveform, polarization, energy uniformity. So it can be used in high power, high conversion efficiency without damping rods, mirrors and crystals.
