Laser spectroscopy – photonics!?
Isn’t that a subject from the past millenium!? By far not!
Studying the interaction between light and matter is not only a technologically highly relevant subject with numerous connections to industry.
Precision spectroscopy of cold gases, trapped ions or solid state materials is internationally highly active and very broad research area. In the last 10 years alone, no less than 14 Nobel prizes were the result of research on or application of topics in the field of photonics.
Course contents:
The lecture gives an introduction to modern methods used in laser-based atomic physics. Besides studying the properties of atoms, the tailored manipulation of the quantum states of atoms and molecules is discussed in detail. The course discusses the basic principles of techniques of spectroscopy and manipulation of atoms etc. using light (coherent vs. incoherent spectroscopy, Doppler free techniques, traps for neutral particles and ions, quantum state control). We cover technical laser equipment like optical modulators or homodyne-heterodyne measurement techniques. We discuss aspects of laser beam characterization, give a thorough introduction to Gaussian optics and optical resonators, and treat in some detail the field of non-linear optics (frequency doubling, non-linear frequency mixing). Further topics can be suggested by the students.
To deepen the understanding of the course content, practical training in the lab and the hands-on experience with spectroscopy experiments will be offered.
The lecture directly builds on the Experimental Physics 5a – Quantum and Atomic Physics course.
