High-Order Harmonic Generation and Plasmonics

2014
Attosecond pulses allow for imaging of very fast processes, like electron dynamics. Stockman et al. suggested to use these pulses in connection with a Photoemission electron microscope (PEEM) to study the ultrafast dynamics of plasmons (Stockman et al. Nat Photonics 1:539–544, 2007).

High order harmonic generation in graphene

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
Single layer graphene (SLG) has remarkable physical properties, with potential interest in the fields of electronics and photonics. While being single-atom thick, SLG presents a rather strong optical response, as a large optical absorption, resonance for all excitation frequencies up to the vacuum UV and, therefore, a strong broadband linear response ...

High-order harmonic generation and ATI

Optical Society of America Annual Meeting, 1991
We have previously developed a two-color above threshold ionization (ATI) model and used it to study the photoelectron spectra and the angular distribution of the photoelectron.1 We present calculations of the photon spectrum from recombination of the electron within the context of this model.

High-order harmonic generation in laser aligned molecules

Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference, 2002
Summary form only given. High-order harmonic generation (HHG) has been widely studied in atoms. More recently it has been shown that molecules introduce a variety of additional features to HHG. In particular, unlike atoms, molecules are not isotropic systems.

Introduction to High-Order Harmonic Generation

2013
Laser invented in 1960 has opened up new research areas in atomic and molecular physics [1-6]. Based on this technology, Franken et al. [7] first demonstrated the frequency doubling in a crystal in 1961, New and Ward [8] observed the third-harmonic generation in gases in 1967, and a few years later Reintjes et al.

Applications of high-order harmonic generation

AIP Conference Proceedings, 2000
We present a review of recent research in Lund on applications of high-order harmonic generation. First, we have used high-order harmonics in spectroscopic studies of atoms and molecules. The experimental technique is based on a pump-probe scheme, where the pump pulse is a high-order harmonic synchronized with a laser pulse (probe).

High-order harmonic generation in plasmas

IEEE Journal of Quantum Electronics, 1997
The phenomenon of harmonic generation by electrons oscillating in high-intensity laser fields is surveyed and assessed as a means of producing short-wavelength radiation. Starting from the seminal early work by Sarachik and Schappert (1970), simple motivatory examples are given of incoherent harmonic generation via nonlinear scattering from single ...
