摘要: The author will give in a first step an overview on current researches in nonlinear optics including characterization of phase-matched and quasi-phase-matched properties, the conception of tunable optical parametric sources and the generation of the of new states of light. In a second step Professor will focus on the last subject. It deals with the generation of triple photons from third order down conversion parametric processes. They performed the classical and quantum theories, and realized the pioneer experiment using a doubly-stimulation configuration in a KTiOPO4 single crystal. Professor will show then the energetic and spectral performances of our generator, and detail their new targets, the final goal being the spontaneous process, i.e. the third order parametric fluorescence.

个人简介：

Benoit Boulanger is Professor at Grenoble University and CNRS - Néel Institute where he is head of the group Materials, Nonlinear Optics &Plasmonics. He has authored over 180 papers in refereed journals and conference proceedings. His work is at the frontiers between nonlinear crystal optics, material engineering and quantum optics. His main achievements concern the crystal growth of KTP compounds, the development of the field factor formalism, the invention of the sphere method, the understanding of gray-tracking in KTP, the development of angular-quasi-phase-matching, and the first demonstration of triple photon generation. Benoit Boulanger is Fellow of the Optical Society of America and the European Optical Society since 2012. He was general co-chair of Non Linear Optics / OSA – Hawaii 2013, and he is Topical Editor for Optics Letters since 2014.He gave the short course Nonlinear Parametric Optics at Advanced Solid State Lasers – Shanghai – 2014. He is Vice-President of the French Optical Society since 2013; he will be President from September 2015.
