Abstract

A near-infrared detecting array is developed combining photoelectric and calorimetric method together to measure CW beam profile of high energy lasers. Detailed structure and functional modules of this system are described. The system is widely sensitive to the wavelength range of 0.9~1.7μm and the power density range of W/cm2～kW/cm2. It has an effective detecting area of 22cm×22cm with a spatial resolution of 1.1cm and a temporal resolution of 20ms. Experiments show that the uncertainty of the total energy measurement is 10% and the uncertainty of the power density distribution measurement is less than 15%.The measuring system has been successfully applied in the measurement for the far-field beam of high energy lasers.
