We constitute a synchronous binary channel system of measuring the energy ofpulsing laser, by using AD and the probe of EM500 energy meter. The design approach of each portion, the method of calibration and checkout for the system were discassed. The result of calibration and checkout indicates that this system is precise and reliable. We can use this system to synchronously measure the energy of pulsing laser in two point of an optical system. Finally the applications of this system in the SRS experiment was presented.
