This paper studies gratings engraved in multilayer dielectric stacks for ultra high intensity laser compressors application. We design various grating profiles with high reflected efficiencies for 1780 l/mm multilayer dielectric gratings (MLD). Each grating is defined to exhibit a different electric field maximum value in the pillars of the grating. A(More)
The article deals with detailed evaluation of heat affected zone in sub-surface layers of the samples made by technology of wire electrical discharge machining. The samples were produced on EDM-WC machine SP 640-P from two different materials, steel and tungsten carbide. The cutting tool was wire brass electrode of 0.25 mm diameter. The aim of this paper is(More)
