Photons, Magnons and Quantum Technologies – Coherent spectroscopy for the study of quantum systems

 

The experimental setup is composed of several laser sources: two synchronized picosecond Ti-Sa lasers (Coherent), one stabilized continuous Ti-Sa laser (MSquared). The cryogenic system is a MyCryofirm helium gas cryostat in closed circuit with high mechanical stability and several optical accesses. Microscope objectives and/or optical fibers placed inside the cryostat allow to focus the beams on the sample and detect the emission. Hanbury-Brown-Twiss and Hong-Ou-Mandel interferometric setups allow to study the emission statistics of single photons as well as the degree of indistinguishability of the photons.
