A DATA-ACQUISITION SYSTEM FOR A HIGH-POWER ND - GLASS-LASER CHAIN

We present here a data-acquisition system for a high-power pulsed Nd:g lass laser oscillator-amplifier chain. This system includes a number o f laser energy monitoring units at various stages of the laser chain, a data-acquisition unit and a control program to control its operation . Each unit in this system is modular and versatile. The system is als o capable of working in the presence of high electromagnetic interfere nce, as is found in operation of high-power pulsed Nd:glass laser syst ems. Any component of this system can be modified independently of the others if the system requirements are changed. The system is ideally suited for lasers with low repetition rate of operation.
