A phase-locked delay device, including: an input port configured to receive an input electromagnetic radiation pulse; said input pulse being to be propagated along a propagation direction and having a first linear polarization different from both a first direction, which is orthogonal to the propagation direction, and a second direction, which is orthogonal to the first direction and the propagation direction; an adjustable Babinet-Soleil module optically coupled to said input port, having a first polarization direction parallel to said first direction. The adjustable Babinet-Soleil module is structured to: provide from the input pulse a first pulse polarized along the first direction and a second pulse collinear to said first pulse and polarized along the second direction, and introduce an adjustable group delay between the first pulse and the second pulse ranging from a minim value &#x394;Tand a maximum value &#x394;T; the maximum value &#x394;Tbeing a value greater than 10 fs.
