The outdoor operation of multi-kilowatt high-power lasers involves the potential hazard exposing human eye and skin to scattered radiation. In present laser safety standards regulations, effects atmospheric off-axis scattering dynamic interaction between beam target object are not adequately represented. Therefore, experimental studies dedicated providing quantitative information on radiation for comprehensive evaluations. With this end in view, a mobile detection system has been developed that relies technical specifications (i.e. entrance aperture field-of-view) regulations. is deployed at German Aerospace Center (DLR) test range Lampoldshausen. Atmospheric experiments performed by placing calibrated under specified angles relative direction determining radiation, i.e. absolute values power. addition, used experiments. these experiments, sensor's versatility demonstrated measuring specularly diffusely from metallic objects. dependence power as function angle, distance, output investigated during laser-matter demonstrate capabilities system.
