We present the first observation of self-amplified spontaneous emission (SASE) in a free-electron laser (FEL) vacuum ultraviolet regime at 109 nm wavelength (11 eV). The observed gain (approximately 3000) and radiation characteristics, such as dependency on bunch charge, angular distribution, spectral width, intensity fluctuations, are all consistent with models for SASE FELs.
Electrons with a linear energy/momentum dispersion are called massless Dirac electrons and represent the low-energy excitations in exotic materials like Graphene Topological Insulators (TIs). characterized by notable properties high mobility, tunable density and, TIs, protection against backscattering through spin-momentum looking mechanism. All those make TIs appealling for plasmonics applications. However, expected to present also strong nonlinear optical behavior. This should mirror...
Laser-based electron sources are attracting strong interest from the conventional accelerator community due to their unique characteristics in terms of high initial energy, low emittance, and significant beam current. Extremely electric fields (up hundreds $\mathrm{GV}/\mathrm{m}$) generated plasma allow accelerating gradients much higher than accelerators set basis for achieving very final energies a compact space. Generating laser-driven high-energy lines therefore represents an attractive...
