Research carried out in the Lebedev Physical Institute (PN Lebedev Physical Institute of the Russian Academy of Sciences), a group led by the chief scientific officer of the Department of laser fusion, Doctor of Physical and Mathematical Sciences Valery Bychenkova are associated with the creation of laser sources of high-energy electrons and ions. Experiments conducted in the collaboration of his group, the Russian Federal Nuclear Center — All-Russian Research Institute of Experimental Physics and the University of Michigan (USA), have shown that irradiation of the gas jet-power laser pulse acceleration of electrons to ultra-relativistic energies is due to the so-called mechanism ionization capture. Using this principle, it is possible to achieve a record high energies — 1.5 GeV, with the length of the acceleration a little more than a centimeter. For comparison: in order to obtain this energy, general linear accelerator must be more than 100 meters.
One of the interesting ideas that were born in the research process, involves the use of high-power femtosecond lasers to simulate some astrophysical phenomena in the laboratory. With these devices, you can simulate the evolution of cosmic gamma-ray bursts — the brightest electromagnetic phenomena occurring in the universe.
Modern high-power femtosecond laser systems are so compact that they can be mounted on the laboratory, the so-called optical, desk. Such systems, known as "desktop laser» (tabletop lasers), promise to open for mankind areas previously considered inaccessible in the laboratory-scale research.
