Lecture
The lecture is in person, HS KPH (nuclear physics bldg), Tues + Thur 12:15 - 13:45.
It will simultaneously be broadcast via zoom, recorded and uploaded to Panopto.

Literature:
* The book of Foot, Atomic Physics is a quite nice introduction in some of the basic concepts of light-atom interaction. You find the first 5 Chapters in this link.
Other good books on atomic physics and atom-light interaction are for example
* van der Straaten, Metcalf: "Atoms and Molecules interacting with light" and
* Hertel, Schulz, Atomic Molecular and Optical Physics 1 and Volume 2. This Vol. 2 has some nice chapters about stuff we'll learn.
* A.E. Siegman "Lasers" is a really good book on the topic. Very comprehensive.
* Demtröder has 2 good books on laser spectroscopy, Vol. 1 and Vol. 2 are available as German ebook
from the library.
* Roberd Boyd, "Nonlinear Optics" covers exactly this. English Ebook at UB

. "Atoms and Molecules interacting with light" )
. Line shape and scattering rate
Homework: Write a (Python / Mathematica) program to solve the OBEs for a 2-level system interacting with light. Reproduce Figures 6.1 and 6.2 in van der Straten & Metcalf.

16 May 23: Polarization ; Lyot filter
Homework: Write a (Python / Mathematica) program to calculate a mutilayer dielectric coating.
Given a set of layer materials and thicknesses, and the wavelength and angle of incoming light, calculate the refected and transmitted fraction by summing up the various electric fields. Use the Sellmeier constants to evaluate the refrective index as a function of wavelength.
23 May 23: Paraxial rays, Gaussian beams and ABCD Matrix
. Paper on our funny target cavity for muonic atom laser spectroscopy.
. Paper on muonic hydrogen spectroscopy and the proton radius, and
. the new muonic 3-He paper
Homework: Write a program for Gaussian beam propagation using ABCD matrices. Python has a bunch of libraries for this. The program should calculate and visualize the Gaussian beam waist while it traverses a set of optical elements.
