    The use of laser range finders (LRF) in two sided exercises extensively increases the quality of training. Nevertheless, this use was banned due to safety regulations. We have issued a new set of safety orders to allow the use of LRF in two sided exercises. The orders state the use of appropriate safety equipment (glasses) and the restriction of use of magnifying direct view optics. The considerations that lead to this set of safety orders are not trivial. We have required that the risk o...

    Spatial Effects of Turbulence on Laser Safety Ranges

    Presented at ILSC 2007

    The effects of atmospheric turbulence on the energy distribution and hence on the safety range of a laser are covered by most military and outdoor laser safety standards. In these standards, a formula for assessing the energy distribution maxima after traveling through a turbulent medium is given. This formula assumes a Gaussian beam in the far field and has no consideration of the effects of the turbulence on the beam geometry. The use of Kolmogorov phase screens to advance the beam through atmospheric turbulence enables an accurate assessment of atmospheric effect...

    Temporal Effects of Turbulence on Laser Safety Ranges

    Presented at ILSC 2007

    The effects of atmospheric turbulence on the energy distribution and hence on the safety range of a laser are covered by most military and outdoor laser safety standards. In these standards, a formula for assessing the energy distribution maxima after traveling through a turbulent medium is given. This formula only considers the spatial distribution of the laser energy. An analysis is made to account for temporal effects such as pulse dispersion and repetitive pulses. This is accomplished by using the turbulence structure function. A simplified calculation procedur...

    A Method has been developed to determine the laser surface danger zone on the earth's spheroid. This method determines where the laser beam cone, defined by the angle , which is half the beam divergence plus the buffer angle, intersects a geometric figure represented by a spheroid that is a good approximation to the shape of the earth. This method is useful to determine the laser surface danger zone on a sea-test range: at the Naval Air Warfare Center Weapons Division (NAWCWD) Point Mugu, California. In addition, this method can be...
