Time-frequency mapping of two-colour photoemission driven by harmonic radiation
Time-frequency mapping of two-colour photoemission driven by harmonic radiation
The use of few-femtosecond, extreme ultraviolet (XUV) pulses, produced by high-order harmonic generation, in combination with few-femtosecond infrared (IR) pulses in pump-probe experiments has great potential to disclose ultrafast dynamics in molecules, nanostructures and solids. A crucial prerequisite is a reliable characterization of the temporal properties of the XUV and …
