Laser-wakefield-accelerated electrons were used to drive an all-optical undulator source, a 5-keV betatron X-ray source and a tunable quasi-monochromatic Compton-X-ray source. Also, we present a phase-contrast tomogram of a fly obtained with the betatron beam.
We model soft x-ray high harmonic generation and propagation driven by mid-infrared lasers. We find that multi-cycle laser pulses are ideal for generating shorter bright isolated attosecond pulses via time-gated phase-matching in high-density extended media.
We examine the interaction of relativistic laser pulses with plasma channels formed in a nitrogen cluster jet. We observe creation of nearly pure N5+ plasma channels and ionization injected wakefield beams with energies >100 MeV.
We present a genetically optimized multi-wavelengths laser based on an aperiodic sampled grating. We show that the grating phases and amplitudes can be optimized to flatten the spectral signature allowing multi-wavelengths operation.
We present a study of features in photoelectron momentum distributions from strong-field ionization of noble gases for few-cycle pulses in the mid-infrared regime and assign characteristics to their classical and quantum mechanical origin.
