Laser-Plasma Coupling: Calculations and Experiments

Laser performance of the SG-III laser facility

SG-III laser facility is now the largest laser driver for inertial confinement fusion research in China. The whole laser facility can deliver 180 kJ energy and 60 TW power ultraviolet laser onto target, with power balance better than 10%. We review the laser system and introduce the SG-III laser performance here.

Experiments on laser driven beatwave acceleration in a ponderomotively formed plasma channel

A 10 ps long beam of 12 MeV electrons is externally injected into a ;3-cm long plasma beatwave excited in a laser ionized hydrogen gas. The electrons have been accelerated to 50 MeV with a gradient of ;1.3 GeV/m. It is shown that when the effective plasma wave amplitude-length product is limited by ionization-induced defocusing ~IID!, acceleration of electrons is significantly enhanced by using...

Laser-driven ultrafast field propagation on solid surfaces.

The interaction of a 3x10;{19} W/cm;{2} laser pulse with a metallic wire has been investigated using proton radiography. The pulse is observed to drive the propagation of a highly transient field along the wire at the speed of light. Within a temporal window of 20 ps, the current driven by this field rises to its peak magnitude approximately 10;{4} A before decaying to below measurable levels. ...
