Evidence of high harmonics from echo-enabled harmonic generation for seeding x-ray free electron lasers.
Echo-enabled harmonic generation free electron lasers hold great promise for the generation of fully coherent radiation in x-ray wavelengths. Here we report the first evidence of high harmonics from the echo-enabled harmonic generation technique in the realistic scenario where the laser energy modulation is comparable to the beam slice energy spread. In this experiment, coherent radiation at th...
متن کاملTuning of high-order harmonics seeding plasma-based x-ray laser
Seeding x-ray lasers with high-order harmonic (HH) radiation has been successfully demonstrated a few years ago [1] and it is under extensive investigation nowadays [2]. The HH spectrum consists of discrete spectral lines at the odd multiples of the frequency of the driving laser pulses. Unfortunately, most of the harmonic lines do not coincide exactly with the wavelength of potential x-ray las...
متن کاملGeneration of High Order Harmonics from H2+ Molecule Ion by Using Homogenous and Inhomogeneous Laser Fields
We solved one dimensional Schrodinger equation in a H2+ molecular environment by using 3 femtosecond homogeneous and nonhomogeneous laser fields. In homogeneous case, we found out that larger inter nuclear distances result in earlier ionization and also more instability in the wave packet. We deducted that the more the instability is, the more modulated the power spectrum will be. So, by choosi...
متن کاملFully Phase Matched High Harmonic Generation in a Hollow Waveguide for Free Electron Laser Seeding
A bright high harmonic source is presented delivering up to 10 photons per second around a central photon energy of 120 eV. Fully phase matched harmonics are generated in an elongated capillary reaching a cut-off energy of 160 eV. The high HHG photon fluence opens new perspectives towards seeding free electron lasers at shorter wavelengths than the state of the art. Characterization of the phas...
متن کاملPolarization shaping of high-order harmonics in laser-aligned molecules
The present work reports on the generation of short-pulse coherent extreme ultraviolet radiation of controlled polarization. The proposed strategy is based on high-order harmonics generated in pre-aligned molecules. Field-free molecular alignment produced by a short linearly-polarized infrared laser pulse is used to break the isotropy of a gas medium. Driving the aligned molecules by a circular...
