Femtosecond dynamics of short-scale-length laser plasmas

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

With a time-resolved pump-probe setup, the dynamical interactions of intense 400-fs laser pulses with a solid target are studied with a time resolution of about 250 fs. The motion of the plasma critical surface is measured by the means of the Doppler shift of the probe laser. It is found that when the average electron quiver energy (mv2 os/2) becomes comparable to the electron thermal energy (kTe), the ponderomotive force of the high-intensity laser significantly reduces the thermal expansion of the laser-plasma.
