Abstract: One of the main obstacles to the uniform laser compression of a fusion target is the plasma formation instability (the Rayleigh –Taylor instability is the most dangerous). In all the schemes considered, the impulsive character is important. In this case, not all possible plasma instabilities are dangerous, but only those that most rapidly increase with time (for example, Rayleigh – Taylor instability).

Keywords: laser, magnetic field, mathematical model, plasma target.
