Abstract: Parameters (thickness, electron density) of the laser target in the form of ultrathin foil are determined that provide maximum ($\sim$ 10%) conversion ratio of short relativistically intense laser pulses into a train of several coherent attopulses. Attopulse amplitude, duration are determined, conversion ratio of laser energy into the energy of attopulses is determined and the possibility of its increase using several successively located targets is shown.

Keywords: ultraintense laser pulse, attopulse, laser plasma, laser target.
