“…Of particular interest to us are experimental investigation on the spatial scattering distribution of horizontally propagating HEL laser beams. Imaging cameras 3 or measurement systems with multiple individual optical sensors 4,5 are used to record the scattered radiation distribution with high spatial resolution. In that publications, however, only time-averaged measured values were presented without analyzing the appearance of particularly strong scattering events on a short time scale.…”

The propagation of a high-energy laser (HEL) beam through the atmosphere causes stray light emission of much higher average intensity than from conventional cw or pulsed laser sources. Particularly interesting are the events of laser emission interaction with aerosol and dust particles, leading to powerful scattered radiation pulses. Their peak power may significantly exceed the average level of the scattered emission and may seriously impact evaluation of nominal ocular hazard distance (NOHD) and thus laser safety aspects of HEL outdoor operations.
