Extreme ultraviolet Fourier-transform spectroscopy with high order harmonics.

چکیده
We demonstrate a new scheme for extreme ultraviolet (xuv) Fourier-transform spectroscopy based on the generation of two phase-locked high-harmonic beams. It allows us to measure for the first time interferograms at wavelengths as short as 90 nm, and open the perspective of performing high-resolution Fourier-transform absorption spectroscopy in the xuv. Our measurements also demonstrate that a precise control of the relative phase of harmonic pulses can be obtained with an accuracy on an attosecond time scale, of importance for future xuv pump-xuv probe attosecond spectroscopy.

Interferometric time delay correction for Fourier transform spectroscopy in the extreme ultraviolet
We demonstrate a Fourier transform spectrometer in the extreme ultraviolet (XUV) spectrum using a high-harmonic source, with wavelengths as short as 32 nm. The femtosecond infrared laser source is divided into two separate foci in the same gas jet to create two synchronized XUV sources. An interferometric method to determine the relative delay between the two sources is shown to improve the acc...

متن کاملSingle-order laser high harmonics in XUV for ultrafast photoelectron spectroscopy of molecular wavepacket dynamics
We present applications of extreme ultraviolet (XUV) single-order laser harmonics to gas-phase ultrafast photoelectron spectroscopy. Ultrashort XUV pulses at 80 nm are obtained as the 5th order harmonics of the fundamental laser at 400 nm by using Xe or Kr as the nonlinear medium and separated from other harmonic orders by using an indium foil. The single-order laser harmonics is applied for re...

Techniques for the production of short wavelengths in the extreme ultraviolet wavelength range aredescribed, spanning low-order harmonic generation in the perturbative regime for narrow bandwidth XUV productionto the plateau-regime with the three-step collisional model for the generation of high harmonics with broadband ultrafastpulses. In addition, the intermediate regime is discus...
متن کاملRamsey-type spectroscopy with high-order harmonics.
We present an experiment where Ramsey-type spectroscopy is applied to autoionizing states of krypton by using the ninth harmonic (88 nm) of a femtosecond Ti:sapphire laser. The ionization process, detected by an electron-energy spectrometer, shows the characteristic quantum interference pattern. The behavior of the fringe contrast compares favorably with a simple essential-state model, whose pa...
