Query: Laser Generated Magnetic Pulses: Hot Electron Propagation in Conducting
  and Dielectric Material   We report experimental evidence of electrostatic inhibition of fast
electrons, generated in a highly resistive material upon irradiation with an
intense ultra-short ($10^{16} W/cm^{2}$, $100 fmsec$) laser pulse. The
experiment involves measurement of temporal evolution of self-generated
magnetic pulses using pump-probe polarimetry. A comparison is made between the
temporal behaviour of magnetic pulses generated with Aluminum and Glass
targets. It is found that in contrast to Aluminium, self-generated magnetic
pulse decays much faster in glass. This is attributed to the absence of return
shielding currents in glass, which results in build up of electrostatic field,
which in turn inhibits the movement of fast electrons. Fitting of experimental
measurements using a one dimensional model, yields estimate of conductivity of
Aluminium and glass, and penetration depth of hot electrons in these materials.
