Expérimental
We propose to pursue the development of a harmonic holographic microscope for single-shot mapping of the second harmonic 3D radiation pattern near samples with nonzero second harmonic susceptibilities. The knowledge of the scattered field (amplitude and phase) in a given plane (that of a camera) allows its reconstruction in any other plane using e.g. the angular spectrum representation of optical fields, and assuming propagation in homogeneous media. The training will be performed under supervision of Yannick De Wilde (CNRS Research Director at Institut Langevin scientist) and co-supervision of his PhD student Serena Goldmann and our collaborator Gilles Tessier (Professor at Sorbonne University). We plan to continue it with a thesis.
