Abstract

A experimental method measuring laser energy and energy distributing of large-aperture beam is presented. The experimental equipment is established. The energy and energy distribution of beam, the beam size is Φ100mm and Φ360mm, are measured. The result show measuring error for laser energy is less than 8%. The energy distribution is basically consistent.
