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…
Tailoring polarisation of attosecond pulses via co-rotating bicircular laser fields
Rambabu Rajpoot, Amol R. Holkundkar, Navdeep Rana +1
The present work introduces a robust way to generate attosecond pulses with tunable ellipticity via high-order harmonic generation by co-rotating bicircular laser fields. T…
Bi-chromatic driver enabled control of high harmonic generation in atomic targets
Rambabu Rajpoot, Amol R. Holkundkar
We investigated the high-order harmonic generation by interacting time-delayed, linearly polarized bi-chromatic laser pulses with the atomic target. The frequency ratio of secondar…
High-order harmonic generation by sub-cycle laser pulses and associated scaling laws
Amol R. Holkundkar, Rambabu Rajpoot, Jayendra N. Bandyopadhyay
We studied the high-harmonic generation by the interaction of sub-cycle laser pulses with the He atom. The sub-cycle pulses are modeled using the complex source vector beam model,…
Polarization control of attosecond pulses using bi-chromatic elliptically polarized laser
Rambabu Rajpoot, Amol R. Holkundkar, Jayendra N. Bandyopadhyay
We study the higher-harmonic generation (HHG) using elliptically polarized two-color driving fields. The HHG via bi-chromatic counter-rotating laser fields is a promising source of…
Controlling resonant enhancement in higher-order harmonic generation
Rambabu Rajpoot, Amol R. Holkundkar, Jayendra N. Bandyopadhyay
We present a method to tune the resonantly enhanced harmonic emission from engineered potentials, which would be experimentally feasible in the purview of the recent advances in at…
Regulating the higher harmonic cutoffs via sinc pulse
Rambabu Rajpoot, Amol R. Holkundkar, Jayendra N. Bandyopadhyay
We theoretically investigate the generation of higher harmonics and the construction of a single attosecond pulse by means of two oppositely polarized sinc-shaped driver pulses. In…
