Photoelectron spectroscopy of 3s3p doubly excited helium dressed with strong near-infrared laser fields
Mizuho Fushitani, Chien-Nan Liu, Yuki Ono +9
We report time-resolved photoelectron spectroscopy of the doubly excited states of helium dressed by an intense near-infrared (NIR) laser field. Using synchronized XUV free-…

Vortex photoelectron holography in strong-field tunneling ionization
Yongkun Chen, Oleg I. Tolstikhin, Toru Morishita +2
Vortex electrons, characterized by a helical phase front, offer unique advantages for probing material structures. Such electrons can be generated via tunneling ionization in stron…
