Abstract

A method of measuring the spatial profile of high energy laser beams with constant temporal characteristics is presented. The Air Force Weapons Laboratory (AFWL) developed this method, known as the 'Target Plate', to measure the irradiance of a near-field laser beam at any given point to assist in the assessment of material effects and system vulnerability to lasers. The Target Plate has been used to measure irradiances of 50 w/cm2 to 912 kW/cm2 on many lasers and a short wavelength arc heater. Software developed for the Target Plate can produce three-dimensional views of the beam along with data files that describe the beam as a set of irradiances versus X-Y coord-inates. This has made the technique useful for incorporating laser beam data into material damage models and optic train heating analysis.
