- W1986827280 abstract "This paper introduces the design of optics, power driver and control system of a high power semiconductor medical laser. The instrument adopts 980nm laser with maximum power output of 2W as therapeutic beam and 670nm laser of 3mW as aiming beam. The laser beams, after being collimated , can either be transmitted directly or be coupled through an optical fiber. In the driver of therapeutic laser, there exist current supply, protection circuit , temperature controller and light power feedback loop. The whole system is controlled by a microprocessor. With appropriate hardware and software, we've achieved , in our driver ,a variety of protection features including the ability to suppress transients and reduce noise, relay shorting protection , soft turn-on , current limit and overvoltage shut-off ,which keep the laser diode from damage. Meanwhile, we've also obtained a continuously adjustable optical power output with high accuracy and stability , both of which are vital to a safe and reliable" @default.
