A.P. Kuznetsov and S.V. GenisaretskayaIII Conference on Plasma and Laser Research and Technologies took place on January 24th until January 27th, 2017 at the National Research Nuclear University "MEPhI" (NRNU MEPhI). The Conference was organized by the Institute for Laser and Plasma Technologies and was supported by the Competitiveness Program of NRNU MEPhI.The conference program consisted of nine sections:• Laser physics and its application• Plasma physics and its application• Laser, plasma and radiation technologies in industry• Physics of extreme light fields• Controlled thermonuclear fusion• Modern problems of theoretical physics• Challenges in physics of solid state, functional materials and nanosystems• Particle accelerators and radiation technologies• Modern trends of quantum metrology.The conference is based on scientific fields as follows:• Laser, plasma and radiation technologies in industry, energetic, medicine;• Photonics, quantum metrology, optical information processing;• New functional materials, metamaterials, “smart” alloys and quantum systems;• Ultrahigh optical fields, high-power lasers, Mega Science facilities;• High-temperature plasma physics, environmentally-friendly energetic based on controlled thermonuclear fusion;• Spectroscopic synchrotron, neutron, laser research methods, quantum mechanical calculation and computer modelling of condensed media and nanostructures.More than 250 specialists took part in the Conference. They represented leading Russian scientific research centers and universities (National Research Centre "Kurchatov Institute", A.M. Prokhorov General Physics Institute, P.N. Lebedev Physical Institute, Troitsk Institute for Innovation and Fusion Research, Joint Institute for Nuclear Research, Moscow Institute of Physics and Tecnology and others) and leading scientific centers and universities from Germany, France, USA, Canada, Japan.We would like to thank heartily all of the speakers, participants, organizing and program committee members for their contribution to the conference.
