Semicondutor Laser Power supply controlled by sing-chip microcomputer

We describe a CW semiconductor laser driver which adopts microprocessor control. The system is composed of stable current source, protection circuit, temperature controller and light power feedback loop. By combining appropriate hardware and software, we have achieved, in our driver, a variety cf protection features including the ability to suppress transients and reduce noise, relay shorting protection, soft turn-on, current linit and overvoltage shut-off. Meanwhile, we've also obtained a continuously adjustable optical power output with high accuracy and stability.
