The talk will give an introduction to X-ray lasers, highlighting the differences between conventional optical lasers and free-electron lasers. The talk has the following structure:
-
The electromagnetic spectrum
-
Creation of light
-
Light from conventional lasers
-
Stimulated emission
-
Population inversion
-
Spatial and Temporal Coherence
-
X-ray lasers of all types
-
Creation of light by accelerating charges
-
The science of x-ray lasers with some of the examples.
In addition to science, I would bring up unrelated other activities that some of us in Uppsala are engaged in: https://www.ambulansertillukraina.se/
