To solve the problem that it is difficult to real-time monitor high power laser power supply

an remote monitoring system based on CompactRIO real-time controller is designed. The controller is developed by using the Laboratory Virtual Instrument Engineering Workbench（ LabVIEW） platform. This system consists of personal computer（ PC） and real-time（ RT） controller and communicates with each other via Ethernet. The real-time controller sends the current information of laser power to PC via Ethernet. PC reads and display the recieved information. In this way

each parameter can be monitored timely. Tests are done for many times and result of tests show that the system can run stably and meet the requirement of monitoring. Operator in charge of it doesn’t have to get to workplace since the state of laser power can be seen on PC timely

which attains the goal of remote control of laser power.
