Direct phonon excitation in semiconductors by ultrashort intense THz radiation Conference Paper uri icon

abstract

  • Ultrashort intense THz radiation generated through laser filamentation in air is employed to directly excite the lattice of AlGaAs semi-insulating crystals. Incoherent as well as coherent phonons are shown to be excited in this way. © 2009 Optical society of America.
