Description
Following the first demonstration of isolated attosecond FEL pulses in 2018 and the Nobel prize in (tabletop) attosecond science in 2023, demand for attosecond x-ray pulses has increased exponentially.
This talk would review recent advances in attosecond pulse generation, including: attosecond lasing at LCLS-II; the first demonstration of attosecond super-radiance; and a measurement of FEL group velocity in the first attosecond pump / attosecond probe experiment at a free electron laser. These advances rely on the novel use of collective dynamics to shape the electron beam.
This talk would also provide an outlook for upcoming opportunities in attosecond science using linear accelerators, including:
HXR attosecond pulses and attosecond beams from plasma wakefield based bunch compression.
