Coherent control of orthogonal continuum states in XUV photoionization
Neha Kukreti, Amol R. Holkundkar
We demonstrate coherent control of orthogonal continuum electron states in the XUV photoionization of atomic hydrogen using polarization-tailored driving fields. By combining polar…
Momentum-space signatures of radial orbital nodes in XUV photoionization
Neha Kukreti, Amol R. Holkundkar
Photoelectron momentum distributions (PMDs) are widely used to probe light matter interactions, yet their angular features are generally assumed to be governed primarily by angular…
High-harmonic generation as a tunneling delay probe
Amol R. Holkundkar
We investigate the feasibility of using high-harmonic generation (HHG) as a complementary probe of tunneling delay in strong-field ionization. By combining time--frequency analysis…
Phase-Controlled Ramsey Interference of XUV Photoelectrons
Neha Kukreti, Amol R Holkundkar
We investigate Ramsey-type quantum interference in photoelectron momentum distributions generated by two time-delayed, linearly polarized extreme-ultraviolet (XUV) laser pulses. Th…
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…
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…
