At focused intensities above 10^18 W/cm^2, a laser pulse accelerates bunches of electrons into a solid target by the v x B component of the Lorentz force. These bunches are separated by half the laser period and hence emit visible light by coherent transition radiation (CTR) at twice the laser frequency (20) as they...

In Inertial Confinement Fusion (ICF), an indirectly driven implosion begins with an acceleration phase when the hohlraum x-rays ablate the shell surface and the capsule starts to converge.

In indirect-drive inertial confinement fusion (ICF) a high-Z enclosure (or "hohlraum") surrounds a low-Z capsule containing DT fuel inside a low-Z spherical shell.
