摘要：

An analytical model and numerical simulations demonstrate that pulses with intensities exceeding 10(22) W/cm(2) may penetrate deeply into the plasma and accelerate efficiently ions in the forward direction. We propose a new scheme for fast ignition of precompressed DT fusion targets by using two laser pulses. The first pulse (or a sequence of several pulses) creates a channel with diameter similar to 30 mu m through the plasma corona up to the fuel density similar to 1 g/cm(3). The second pulse with a higher intensity accelerates the deuterium and tritium ions at the head of this channel. The overall ignition energy is similar to 100 kJ.
