Paper Abstract

A synthesis of the calorimetric and photoelectric method on the high energy laser beams measurement is presented. Data fusion of the two kinds of detector units is achieved with real-time scaling onsite. A set of compound diagnostic system is developed for the large area laser beam intensity distribution measurement, which is mainly composed of 256 calorimetric detectors, 120 photoelectric detectors, multi-channel data sampling module and one central processing computer. The total energy of the laser beam is accurately measured with calorimetric detectors, and the spatial intensity distribution with high temporal resolution is given by the photoelectric detectors. With the merits of energy accuracy and the temporal resolution based on the two kinds of detector units, the compound diagnostic system can be used to measure accurately the far-field temporal and spatial distribution of high energy laser beams.
