Efficient Coherent XUV Generation and Manipulation in Microfluidic Glass Devices
Anna Gabriella Ciriolo, Rebeca Martínez Vázquez, Gabriele Crippa +12
The development of compact and bright XUV and soft X-ray sources based on high-order harmonic generation is boosting advances towards understanding the behavior of matter with extr…
High-harmonic generation in a strongly overdriven regime
B. Major, K. Kovács, E. Svirplys +6
High-harmonic generation (HHG) normally requires a careful adjustment of the driving laser intensity (typically W/cm) and gas medium parameters to enable go…
Detailed study of quantum path interferences in high harmonic generation driven by chirped laser pulses
Tamás Csizmadia, Lénárd Gulyás Oldal, Peng Ye +7
We investigate the electron quantum path interference effects during high harmonic generation in atomic gas medium driven by ultrashort chirped laser pulses. To achieve that, we id…
Compact intense extreme-ultraviolet source
Balázs Major, Omair Ghafur, Katalin Kovács +4
High-intensity laser pulses covering the ultraviolet to terahertz spectral regions are nowadays routinely generated in a large number of laboratories. In contrast, intense extreme-…
Propagation-assisted generation of intense few-femtosecond high-harmonic pulses
B. Major, M. Kretschmar, O. Ghafur +11
The ongoing development of intense high-harmonic generation (HHG) sources has recently enabled highly nonlinear ionization of atoms by the absorption of at least 10 extreme-ultravi…
Three ways to select from two attosecond pulses
Katalin Kovacs, Valer Tosa
We demonstrate that by filtering high harmonics it is possible to obtain two different single attosecond pulses (SAP) resulting from naturally separated spectral domains formed dur…
The effect of plasma-core induced self-guiding on phase matching of high-order harmonic generation in gases
Balázs Major, Katalin Kovács, Valer Tosa +3
In this work we numerically study a self-guiding process in which ionization plays a dominant role and analyze its effect on high-order harmonic generation (HHG) in gases. Although…
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…
Influence of generalized focusing of few-cycle Gaussian pulses in attosecond pulse generation
Ebrahim Karimi, Carlo Altucci, Valer Tosa +2
In contrast to the case of quasi-monochromatic waves, a focused optical pulse in the few-cycle limit may exhibit two independent curved wavefronts, associated with phase and group…
Single attosecond pulse from terahertz-assisted high-order harmonic generation
Emeric Balogh, Katalin Kovacs, Peter Dombi +5
High-order harmonic generation by few-cycle 800 nm laser pulses in neon gas in the presence of a strong terahertz (THz) field is investigated numerically with propagation effects t…
Separation of Target Structure and Medium Propagation Effects in High-Harmonic Generation
Cheng Jin, Hans Jakob Worner, V. Tosa +6
We calculate high-harmonic generation (HHG) by intense infrared lasers in atoms and molecules with the inclusion of macroscopic propagation of the harmonics in the gas medium. We s…
