We report on the characteristics of coherent synchrotron radiation (CSR) as a source for spectroscopy. The optimization of the source and the resulting figures of merits in terms of flux, signal to noise, spatial distribution and spectral and temporal distribution are presented together with a spectroscopic application. The emission of THz during the slicing operation is also described. The conclusion...
We present experimental and numerical results on Terahertz coherent synchrotron radiation obtained in the beamline AILES at the synchrotron SOLEIL. Depending on the storage ring configuration and on the electron bunch current we observed either stable or instable signals.
We consider the suppression of the so-called "turbulent regimes" in optical systems with advection. It is well known that spatiotemporal systems submitted to advection can undergo a convective instability above a critical value of the drift parameter. The result is a hypersensivity to noise leading to spatiotemporal erratic regimes called noise sustained structures or "optical turbulence"...
Summary form only given. In this paper, a coherent narrowband tunable terahertz emission from an electron bunch is reported, transposing a technique well-known in nonlinear optics: interaction with laser pulses containing an internal modulation. The modulated pulses are produced from a titanium-sapphire laser using chirped pulse beating, and are focused on the electron beam, inside an undulator. The...
