| Abstract: | We describe a laser driver which can drive a group of parallel connected semiconductor lasers and the driver adoptsmicroprocessor control. The system is composed of modulatable stable current source, protection circuit and light powerfeedback loop. By combining appropriate hardware and software, we have achieved, in our driver, a variety of protectionfeatures including the ability to relay shorting protection, soft turn-on current limit and overvoltage shut-off. Meanwhile, we'realso obtained adjustable optical power outputs with high accuracy and stability and the parallel connected semiconductorlasers are independent. |
