Sub-cycle pulse control of holographic and non-holographic electron interferences
Rambabu Rajpoot, Eiji J. Takahashi
We investigate the influence of sub-cycle laser pulses on holographic and non-holographic intracycle interferences by analyzing the photoelectron momentum distributions of helium u…

Towards intense single-digit attosecond pulses with a 100-mJ-class mid-infrared sub-cycle laser
Kaito Nishimiya, Rambabu Rajpoot, Eiji J Takahashi
The duration of isolated attosecond pulses created via high-order harmonic generation is determined by the number of optical cycles in the driving laser. Achieving shorter attoseco…

Systematic analysis of an attosecond pulse generation by a sub-cycle laser field
Rambabu Rajpoot, Eiji J. Takahashi
We investigated the influence of sub-cycle driving fields on high-order harmonic generation (HHG), with a focus on intrinsic chirp, carrier-envelope phase (CEP), and number of lase…
