International audience; Barium germano-gallate (BGG) glasses are attractive glass hosts for photonic applications in the mid-infrared region up to 6 µm. In this work, we investigate the photosensitivity of such glasses under femtosecond laser, with

International audience; We present a time-of-flight tomography method for exceeding the naïve axial (i.e., depth) resolution limit of terahertz (THz) deconvolution by autoregressive spectral extrapolation (AR) based on the modified covariance method

In this Letter, we demonstrate that the far-field terahertz (THz) beam generated from a Ti:Sapphire two-color laser-induced filament can exhibit a conical or Gaussian distribution, depending on the filtering experimental conditions. Using both an inc
