Abstract

A simple method is presented for determining the nominal ocular hazard distance from non-Gaussian laser beams. The simplified method currently used for laser safety calculations when determining the laser beam diameter as a function of distance produces errors in the near field. The irradiance or radiant exposure of multimode and non-Gaussian laser beams in the near field may be calculated more precisely by the use of a simple proposed relationship with easily determined parameters.
