Operation principles and electrical models of the Rogowski coil used as ordinary CT (current transducer) to measure the short pulse and large amplitude currents of the high-power laser source are presented. Influence induced by both the structure and electromagnetic parameters of the coil to the measurement error characteristics of the CT are analyzed. Design criterions of optimizing structure and electromagnetic parameters of the coil are proposed.
