Abstract: 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 ?Tm and a maximum value ?TM; the maximum value ?TM being a value greater than 10 fs.

Abstract: A system for generating signals for Raman vibrational analysis, particularly for a CARS microscope or spectroscope of an external specimen, the system including a laser source capable of emitting at least one fundamental optical pulse in a first band of fundamental frequencies including at least one first and one second fundamental frequencies; a second-harmonic generating system including at least one nonlinear optical crystal for converting the at least one fundamental optical pulse into a first and a second-harmonic optical pulse; and a Raman vibrational analysis apparatus capable of receiving the first and second second-harmonic pulses and direct them toward the specimen.
