Field strength scaling in quasi-phase-matching of high-order harmonic generation by low-intensity assisting fields
Emeric Balogh, Katalin Varjú
High-order harmonic generation in gas targets is a widespread scheme used to produce extreme ultraviolet radiation, however, it has a limited microscopic efficiency. Macroscopic en…
Scale-invariant nonlinear optics in gases
C. M. Heyl, H. Coudert-Alteirac, M. Miranda +8
Nonlinear optical methods are becoming ubiquitous in many areas of modern photonics. They are, however, often limited to a certain range of input parameters, such as pulse energy a…
Genetic optimization of attosecond pulse generation in light-field synthesizers
E. Balogh, B. Bódi, V. Tosa +3
We demonstrate control over attosecond pulse generation and shaping by numerically optimizing the synthesis of few-cycle to sub-cycle driver waveforms. The optical waveform synthes…
Quasi-phase-matching high-harmonic radiation using chirped THz pulses
Katalin Kovács, Emeric Balogh, János Hebling +2
High-order harmonic generation in the presence of a chirped THz pulse is investigated numerically with a complete 3D non-adiabatic model. The assisting THz pulse illuminates the HH…
A case study for terahertz-assisted single attosecond pulse generation
Emeric Balogh, Katalin Kovács, Valer Tosa +1
We numerically investigate the use of strong THz radiation in assisting single attosecond pulse generation by few-cycle, 800 nm laser pulses. We optimize focusing conditions to gen…
Application of High Intensity THz Pulses for Gas High Harmonic Generation
Emeric Balogh, József A. Fülöp, János Hebling +3
The main effects of an intense THz pulse on gas high harmonic generation are studied via trajectory analysis on the single atom level. Spectral and temporal modifications to the ge…
