We show the laser-driven acceleration of unprecedented, collimated (2 mrad divergence), and quasi-monoenergetic (25% energy spread) electron beams with up to 50 MeV at 1 kHz repetition rate. The laser driver is a multi-cycle (15 fs) optical parametric chirped pulse amplification system, operating 26 mJ (1.7 TW). scalability technology reported in this work pave way toward developing high-brilliance x-ray sources for medical imaging innovative devices brain cancer treatment represent step...
Abstract Ultrafast electron dynamics drive phenomena such as photochemical reactions, catalysis, and light harvesting. To capture in real-time, femtosecond to attosecond sources are extensively used. However, an exact match between the excitation photon energy a characteristic resonance is crucial. High-harmonic generation advantageous terms of pulse duration but limited spectral tunability vacuum ultraviolet range. Here, we present monochromatic source continuously tunable around 21 eV...
