The invention concerns a laser amplification system comprising a pumping device and at least one thick amplifier disc having a first face, which is reflective at the wavelengths of a pulsed laser beam of the laser amplification system and of a pump beam of the pumping device, as well as at least one heat-dissipation component to which this first face of the amplifier disc is firmly secured, the saturation fluence of the active medium of the amplifier disc being equal to or less than 3 J&#xb7;cm.

The invention relates to a laser cavity with central extraction by polarisation for coherent coupling of intense intra-cavity beams. The laser cavity () according to the invention comprises an extraction unit () with central extraction, which divides the laser cavity () longitudinally into two functional portions (P, P), namely a first portion (P) including the active components (), which amplifies the laser beams (), and a second portion (P) which performs coherent coupling of the laser beams ().
