Dynamics of picosecond-laser-pulse plasmas determined from the spectral shifts of reflected probe pulses
The evolution of density profiles in plasmas produced by 10{sup 14}-W cm{sup {minus}2}, 1-ps, 580-nm-wavelength laser pulses has been determined from spectral shifts imposed on a reflected picosecond probe pulse. The shifts are caused by two mechanisms: hydrodynamic expansion and ionization front mo...

Summary: | The evolution of density profiles in plasmas produced by 10{sup 14}-W cm{sup {minus}2}, 1-ps, 580-nm-wavelength laser pulses has been determined from spectral shifts imposed on a reflected picosecond probe pulse. The shifts are caused by two mechanisms: hydrodynamic expansion and ionization front motion. Both time-resolved expansion velocities and ionization rates are inferred from the spectral shifts and are compared to one-dimensional hydrodynamic simulations. |
