A novel approach is proposed to the design and fabrication of focussing systems for laser material processing applications, especially for those where compactness, light weight, low volume and low cost fabrication are desired. The focussing systems described in this paper are designed to be remotely operated by a robot within irradiated environments for decommissioning of nuclear facilities. The laser cutting systems which have been developed are based solely on surface relief diffractive optical elements designed and optimized by computer and fabricated by conventional microlithographic technologies.
