Description
The SYLOS SHHG beamline at ELI-ALPS is designed to investigate the interaction of relativistic intensity (> $10^{18} W/cm^2$) few-cycle (pulse-width ~ 8 fs) laser pulses with near-solid-density surface plasma (density > $10^{21} cm^{-3}$), and explore the plasma dynamics and subsequent generation of secondary particles and radiations resulting from the interaction [1, 2]. The beamline is driven by the SYLOS 3 [13 TW; 9 fs; 1 kHz (tunable)] and the SEA [2 TW; 12 fs; 10 Hz] laser systems, and consists of multiple vacuum chambers housing several sub-systems. It is equipped with several state-of-the-art laser, imaging, and secondary particle and radiation characterization systems. The key areas of investigation include the study of relativistic dynamics of surface plasma interaction, high-harmonic generation and relativistic electron measurements, and applied plasma optics, to name a few.
The poster would elucidate the available diagnostics present in the beamline showing typical measurements of pulse-width (in-vacuum), laser profile, wave-front, CEP stabilization, and focal spot characteristics (spot size and stability). The available target system would be explained. Typical high-harmonic spectrum measurements using a flat-field grating in tandem with a multi-channel-plate and phosphor assembly would be demonstrated. Typical examples of User experiments performed in the beamline would be outlined, and future possibilities would be discussed.
