Spatial hole burning in thin-disk lasers and twisted-mode operation
Karsten Schuhmann, Klaus Kirch, Francois Nez +3
Spatial hole burning prevents single-frequency operation of thin-disk lasers when the thin disk is used as a folding mirror. We present an evaluation of the saturation effects in t…
The proton radius puzzle
J. J. Krauth, K. Schuhmann, M. Abdou Ahmed +49
High-precision measurements of the proton radius from laser spectroscopy of muonic hydrogen demonstrated up to six standard deviations smaller values than obtained from electron-pr…
Theory of the n=2 levels in muonic helium-3 ions
Beatrice Franke, Julian J. Krauth, Aldo Antognini +3
The present knowledge of Lamb shift, fine-, and hyperfine structure of the 2S and 2P states in muonic helium-3 ions is reviewed in anticipation of the results of a first measuremen…
