This type of power supply with single lamp and single case, using touch screen, is a new type of power supply combined with charging box and discharging box. The parameters of pulsed control power supply are kept in the memory of touch screen, 100 groups of discharging parameters included. Lower machine adopts 32-bit CPU to realize pulsed power supply control quickly. The precision of current control can reach 0.1A. which makes it more stable. Users can make a program to the wave- form and parameters of various lasers by touch screen, so that it can meet almost all the needs of practical application. This kind of laser power supply, which can intelligently control the working current of xenon lamp, repetitive working frequency and pulse width, is the ideal configuration of the lamp pumped Nd: YAG pulsed laser. It is of the characteristics of working stable work, strong control function, small volume, convenient operation and easy maintenance, etc.
