Project Content
Electromagnetically induced transparency (EIT) is a powerful tool in atomic physics and nonlinear optics that enabled slowing down and eventually stopping light pulses. In our project, we will utilize EIT towards creating sensors and optical storage devices. The project will start with setting up a laser system together with its stabilization electronics. It will be then followed by optical spectroscopy and identification of electronic levels that will be used in EIT experiments. 
Tasks for Interns
Setting up the basic optical components and perform an initial characterization of the experimental setup. This will involve Labview control of experimental electronics, precise coupling of laser beams into optical fibres and optimizing the beam parameters (focusing distance, beamwidth etc.) for the eventual experiment.
Academic Level
Advanced undergraduate students (3rd or 4th year)
  • Basic knowledge in optics; 
  • Courses in quantum mechanics; 
  • Python or LabView knowledge; 
  • Prior laboratory experience (desired); 
  • Very good command of English
Expected Preparation
  • Reading the basics of EIT technique and atomic spectroscopy; 
  • some basic exercises in LabView and/or Python.
