摘要：
Hole boring and fast ignition seem to exclude each other: When there is hole boring, no ignition occurs, and vice versa. The laser beam pressure only causes a more or less deep cone-shaped critical surface that leads to better guidance of the beam and to improved laser-plasma coupling. At laser wavelengths of the order of I mum, successful fast ignition requires strong anomalous laser beam-pellet coupling.
