A model of laser power supply is proposed to offer multiple stable currents by one driver. A pulsewide-modulator (PWM), a push-pull driver, and a high-frequency transformer compose the main circuit of switch laser power supply, and it is used to realize initial stability of high-voltage. Each load circuits of switch laser power supply is mainly made up of a proportional integrator, a comparison amplifier, a photoelectric coupler and a highvoltage adjusting tube, it stabilizes current independently. It has been proved in the experiment that each load circuit hadn't influence on others when the whole laser power supply works and every current in the load circuit had the precision of 1‰.
