Paper Abstract

Diffractive beam samplers have been employed for some time on the HELEN laser at AWE. The phase gratings combine two functions viz. sampling and focusing in one element. The weak phase modulation generates low power diagnostic beams from which energy measurements have been made. This paper reports on further beam characterization measurements of the imaging properties of these components by recording far field and near field intensity distributions of beams up to 200mm diameter.
