Mise en place d'un polarimètre de Mueller achromatique dans le domaine du visible en régime laser impulsionnel

Abstract : Polarimetry technique allows one to study the changes induced by a physical system in the polarisation of electromagnetic waves. As its optical response is greatly affected by the polarisation state and wavelength of the incident light, a class of powerful polarimeters has been developed to measure the polarimetric response of a sample over a wide spectral band. Such a device, therefore, allows one to greatly increase the number of data about the sample of concern. The polarimeter of that sort we developed and implemented is operating with a pulse source. Moreover, by running a novel and theoretical model to describe the compensated waveplates used we focused on the reduction of systematic errors. This calibration procedure led us to develop a compensated-waveplate characterisation bench. Then, a statistical study allowed us to greatly reduce and quantify the residual errors inherent in a measurement. Key words : Polarization, Spectroscopic polarimeter, Stokes-Mueller formalism, Calibration, Systematic and statistical errors.
