Abstract

Laser damage testing of binary phase diffractive-optic components has been carried out at 1064 nm with 0.5 ns pulses. The surface relief components are produced by etching a fused silica substrate. The results show damage thresholds approaching that of polished fused silica. The design and fabrication of the diffractive-optic components for use with the HELEN multi- terrawatt Nd glass laser system at AWE is briefly described. The components under test were focusing beam samplers and harmonic separation filters.
