Abstract:

Aim 1. To measure simultaneously the spatial and the temporal structure of an isolated attosecond pulse while also simplifying attosecond metrology so it becomes more widely accessible. Result This goal was completely accomplished. Aim 2 To exploit few-cycle infrared radiation to create shorter duration attosecond pulses. Result We currently reach photon energies 500 eV but without phase control for the 1.8 micron driver. Aim 3 To compare attosecond gating methods, selecting the most efficient way to produce the highest power or the shortest duration attosecond pulses. Results We have adapted the attosecond lighthouse to gases and confirmed isolated attosecond pulse production with an IR driver. Aim 4 To use the quantum path interference, present in any attosecond pulse, to resolve the strongly-driven attosecond time-scale electron dynamics in selected ions. Results After discussions with the Program Manager, this aim have been modified to concentrate on harmonics generation in solids
