Efficient ignition of fusion using PW-ps laser pulses for ultrahigh acceleration of plasma blocks
Fusion Engineering（2013）
Abstract
Physics defines the reasons why laser driven ICF by laser pulses of nanosecond duration is basically different from the use of picosecond length. High intensity picoseconds laser pulses transfer energy directly into kinetic energy of plasma blocks without thermal losses, without delays by collisions and with exclusion of most instabilities. Following the long known theory by the nonlinear (ponderomotive) force, it was predicted that the plasma receives an ultra-high predicted acceleration first measured by Sauerbrey and theoretically confirmed in all details. Interaction of the plasma blocks with solid state fusion fuel should generate a Chu-Bobin fusion flame. Usng hydrodynamics with separate electron and ion fluids, detales properties can be studied about shock generation, and the varying velocity of the flame fronts far above 1000 km/s for high gains.
