The European Commission has approved French aid (State Aid No. NN86/95) awarded to the SOPRA and LASERDOT companies for a EUREKA research programme entitled "EU205-EXIMER". The objective of this programme is to define and develop the use of excimer lasers. These lasers have the following characteristics: - Short wave lengths leading to greater absorption and possibility for a variety of photochemical effects; - Short impulse duration allowing very localized, transitory effects. The work carried out has focused on developing this laser source but also on developing the optical components for the transport of the laser beam and on studying its possible industrial applications. The research is, moreover, aimed at extending the industrial use of these lasers, in particular in electronics and, in the medium-term, in other disciplines such as mechanics and industrial cleaning. The total investment required by the project amounts to ECU 13.33 million over a period of 8 years commencing in 1987. The aid in question accounts for 50% of basic industrial research costS and for 15.9% of applied research/development costs. The Commission considers that this aid is acceptable in view of its compatibility with Commission policy on aid to R&D.
