Intensive Week - Laser Cooling

The intensive week will give an introduction to the field of laser cooling. For a whole week, morning lectures and seminars will be complemented by afternoon lab-work to investigate tools, apply methods and realize some of the phenomena that are discussed theoretically.


  • Laser sources in theory and experiment - we will construct a laser based on a new ultra-stable design. Furthermore we will experimentally compare the laser properties of various designs
  • Laser spectroscopy and locking schemes in theory and experiment - we will setup and compare .
  • Laser cooling - we will experimentally realize an ultra cold sample of matter in a magneto-optical trap.
  • We will discuss the foundations of selected laser cooling schemes, based on, for example, Raman sideband transitions or electro-magnetically induced transparency.
