“…On the other hand, creation of high energy density plasmas in the laboratory is possible by virtue of intense laser-solid interactions 1,3 which can lead to the realization of dynamic compression of the material achieving much higher pressures than those in diamond anvil cells 2 . The technique of chirped pulse amplification 4 produces intense ultrashort laser pulses on a table top and has spurred controllable exploration of 'extreme conditions' of matter [5][6][7][8][9][10][11][12][13][14][15][16][17] . The temporal dynamics of ultrashort laser-plasma interactions have just begun to be explored in overdense and near solid density plasma [10][11][12] .…”

Ultrafast pump-probe reflectometry and Doppler spectrometry of a supercritical density plasma layer excited by 10 17 − 10 18 W/cm 2 intensity, 30 fs, 800 nm laser pulses reveal the interplay of laser intensity contrast and inward shock wave strength. The inward shock wave velocity increases with an increase in laser intensity contrast. This trend is supported by simulations as well as by a separate independent experiment employing an external prepulse to control the inward motion of the shock wave. This kind of cost-effective control of shock wave strength using femtosecond pulses could open up new applications in medicine, science, and engineering.

“…The challenge for the WDM regime is apparent from long-standing discrepancies between theoretical models and measurements of the electrical conductivity [14][15][16][17][18][19][20][21][22][23][24][25]. The theoretical studies are complex and include screened Coulomb forces that dominate interactions between ions while electrons are partially to fully degenerate.…”
