“…One of the possible ways to solve the task of fabricating large-sized optical elements with the prescribed dopant distribution in the bulk of the host is the employment of the ceramic synthesis of laser media [12][13][14][15][16]. Impressive progress has been achieved using this technique for fabrication of active laser elements based on yttrium aluminum garnet doped with neodymium ions [17][18][19]. This technology is also undoubtedly promising for the development of high-power IR lasers based on iron-doped zinc chalcogenides.…”

The characteristics of an Fe 2+ :ZnSe laser at room temperature and its active elements with undoped faces were studied. Polycrystalline elements with one or two diffusion-doped internal layers were obtained by the solid-state diffusion bonding technique applied to chemical vapor deposition grown ZnSe plates preliminary doped with Fe 2+ ions in the process of hot isostatic pressing. A non-chain electric-discharge HF laser was used to pump the crystals. It was demonstrated that increasing the number of doped layers allows increasing the maximum diameter of the pump radiation spot and the pump energy without the appearance of transversal parasitic oscillation. For the two-layer-doped active element with a diameter of 20 mm an output energy of 480 mJ was achieved with 37% total efficiency with respect to the absorbed energy. The obtained results demonstrate the potential of the developed technology for fabrication of active elements by the solid-state diffusion bonding technique combined with the hot isostatic pressing treatment for efficient IR lasers based on chalcogenides doped with transition metal ions.
