Polytekhnicheskaya 26, St. Petersburg, 194021, Russian Federation In plasmas, the relativistic flying mirrors are thin and dense electron or electron—ion layers accelerated by the high intensity electromagnetic waves up to velocity close to the speed of light in vacuum; in nonlinear-media the refraction index modulations are induced by a strong electromagnetic wave. The reflection of the electromagnetic wave at the relativistic mirror results in its energy and frequency change. In the counter-propagation configuration the frequency of the reflected wave is multiplied by the factor proportional to the gamma-factor squared. This scientific area promises the development of the sources of ultrashort
