摘要：

We present theory for the laser-assisted photoelectric effect (LAPE) from metal surfaces in combined extreme ultraviolet attosecond and near-infrared femtosecond pulses. We discuss how LAPE with short pulses is used to make time-resolved measurements. We propose the use of reference states located outside the metal surface to allow for measurements of the absolute travel time of electronic wave packets formed inside the metal and to the surface. Finally, we study the variation in the magnitude of laser-induced sidebands with the length of the laser pulse.
