Laser path adjusting system for laser experiments based on LabVIEW

For the purpose of overcoming the disadvantages, such as low adjusting efficiency and complicated operating procedures, in most of current ultra-short and ultra-high-intensity laser experiments, an integrated and simple system for laser path adjusting was designed based on LabVIEW software. This system was consisted of three modules, which were named as laser spot acquiring module, laser path position adjusting module and industry computer respectively. In this system, the pointing of laser path was decided by the position of laser incident on CCD camera, and the adjusting of light path in vacuum was accomplished by a person-machine interface. Meanwhile, simultaneous multi-route running has been achieved in this system, and moving stage controllers of different models or communication styles have been integrated in the same interface. Experiments show that this system could be a better choice for more convenient adjusting of laser path and higher efficiency of ultra-short and ultra-high-intensity laser experiments.
