Study of ultraintense laser propagation in overdense plasmas for fast ignition
Laser plasma interactions in a relativistic regime relevant to the fast ignition in inertial
confinement fusion have been investigated. Ultraintense laser propagation in preformed
plasmas and hot electron generation are studied. The experiments are performed using a
100 TW 0.6 ps laser and a 20 TW 0.6 ps laser synchronized by a long pulse laser. In the
study, a self-focused ultraintense laser beam propagates along its axis into an overdense
plasma with peak density 10 22/cm 3. Channel formation in the plasma is observed. The …
