Short title: Next-generation lasers using self-organizing dynamic holographic cavity. Full title: Investigation of basic principles, temporal regimes and possible applications of a new kind of solid-state and diode lasers with cavity formed

Ziel

The creation of powerful laser sources with high spatial quality and high efficiency is one of the fundamental problems and current limits of laser physics and technology. This project aims to define a new solution to this problem by developing novel self-organizing principles and technology that allow lasers to self-compensate for beam degradation. The industry-related importance of our project is linked to its main goal: the solution of a very important problem of laser engineering - that is, the creation of high power industrial lasers with good beam quality. The project focuses on developing diode-pumped solid-state laser systems at average powers up to several hundreds of Watts and with low divergence and that will find many applications in precision technologies (such as drilling of small apertures, cutting and pointing thermo-hardening of metals, treatment of ceramics and other materials), free-space and fibre optical sensing and communications, medicine and others. A more ambitious direction of the project will be to design new realizations whereby diode laser systems that can operate at high power and low divergence. If arrays of incoherent and independent diode emitting regions can be made to self-organize into a coherent mode of operation this would provide a radical breakthrough in high power diode technology allowing the direct use of diode lasers to be exploited in applications that currently use much less efficient laser systems.

The present project unites research efforts of 6 scientific teams from 4 European countries (Russia, Belarus, UK and France) with expertise underpinning the success of this project: (1) a team from Institute of Applied Physics of the Russian Academy of Science (RAS) in Nizhnii Novgorod, headed by Dr. O.L. Antipov; (2) a group from General Physics Institute of the RAS in Moscow, headed by Prof. I.A. Shcherbakov; (3) a team from Nizhnii Novgorod State University, headed by Prof. A.A. Andronov; (4) a team of Institute of Physics of the National Academy of Sciences of Belarus from Minsk, headed by Prof. E.I. Ivakin; (5) a UK group from Imperial College from London, headed by Dr. M.J. Damzen; (6) and a French group from University of Caen, headed by Prof. R. Moncorge. These teams include specialists in experimental nonlinear optics and laser physics, theoretical and numerical analysis, laser engineers and producers of solid-state laser materials and semiconductor lasers. The teams have established track record of good international collaboration and have obtained world-leading scientific results.
