Abstract: A short, tutorial introduction to some basic concepts of laser-plasma interactions at ultra-high intensities is given. The selected topics include (a) elements of the relativistic dynamics of an electron in electromagnetic fields, including the ponderomotives force and classical radiation friction; (b) the “relativistic” nonlinear optical transparency and self-focusing; (c) the moving mirror concept and its application to light sail acceleration and high harmonic generation, with a note on related instabilities; (d) some specific phenomena related to the absorption of energy, kinetic momentum and angular momentum from the laser light.
