Optics and photonics. Lasers and laser-related equipment. Test methods for laser beam power (energy) density distributionWhat is this standard about? This document specifies methods by which the measurement of power (energy) density distribution is made and defines parameters for the characterization of the spatial properties of laser power (energy) density distribution functions at a given plane. The methods given in this document are intended to be used for the testing and characterization of both continuous wave (cw) and pulsed laser beams used in optics and optical
