Plasmascopy of ultrafast hot charges in solids
Dmitry A. Zimin, Raja Sen, Muhammad Qasim +2
We demonstrate an electric field-resolved approach for probing ultrafast dynamics of photoinjected charges in solids. Direct access to the electric field of few-cycle pulses enable…

Transient optical gain in strong-field-excited solids
Muhammad Qasim, Dmitry A. Zimin, Vladislav S. Yakovlev
Multiphoton excitation of a solid by a few-cycle, intense laser pulse forms a very non-equilibrium distribution of charge carriers, where occupation probabilities do not necessaril…

Ensemble properties of charge carriers injected by an ultrashort laser pulse
Muhammad Qasim, Michael S. Wismer, Manoram Agarwal +1
The average effective mass of charge carriers produced by an intense ultrashort laser pulse in a transparent solid increases significantly as the excitation mechanism changes from…
