Design of kJ pulse laser control system

An optimized stability control system is revealed basing on the research of the working environment of massive high power laser facilities. The Ethernet and EtherCAT bus serve as the basic framework. An open and heterogeneous computer control system is designed with software basing on a three-layer structure with CORBA middleware and C/S call mode. The system can overcome the adverse electromagnetic environment and dispersed objectives in the kJ laser facility. All the objects can be controlled under certain sequence to satisfy the demands of physical experiments.
