Megagauss Magnetic Field Generation and Plasma Jet Formation on Solid Targets Irradiated by an Ultraintense Picosecond Laser Pulse

Magnetic field measurements in laser-produced plasmas via proton deflectometry

“…[3][4][5][6] The measurement of laser-produced magnetic fields in conditions relevant to "conventional" ICF ͑i.e., with laser intensities up to ϳ10 15 W cm −2 ͒ has been limited so far to the outer "coronal" plasma region ͑with densities up to 10 20 cm −3 ͒, where magnetic fields of amplitude up to the order of 10 2 T generated due to the ٌ ជ T e ϫ ٌ ជ n e mechanism 1 have been identified via optical polarimetry. 1,7,8 Denser plasma regions could not be optically probed because of their high index of refraction.…”

Plasma Jets Driven by Ultraintense-Laser Interaction with Thin Foils

“…3(b)] by acting on the electrons pinches the plasma jet towards the axis. The bunch transverse size is approximately equal to the waist of the irradiated region, 10 m. The magnetic field can contribute significantly to the long term pinching of the ejected plasma plumes [24]. Since the ion momentum distribution along the x direction shown in Figs.…”

Laser-Generated Ultrashort Multimegagauss Magnetic Pulses in Plasmas

“…To our knowledge, only one laboratory has hitherto reported [11] pump-probe magnetic fields measurements on picosecond time scales (using 1 ps duration laser pulse at normal incidence). However, these measurements were confined to an under-dense plasma region (n e = 4 × 10 19 cm −3 ) and the diagnostics employed limited the temporal resolution to ∼ 3 ps.…”
