Measuring the temperature and heating rate of a single ion by imaging
Bharath Srivathsan, Martin Fischer, Lucas Alber +3
We present a technique based on high resolution imaging to measure the absolute temperature and the heating rate of a single ion trapped at the focus of a deep parabolic mirror. We…

Shifting the phase of a coherent beam with a Yb ion: influence of the scattering cross section
Martin Fischer, Bharath Srivathsan, Lucas Alber +3
We discuss and measure the phase shift imposed onto a radially polarized light beam when focusing it onto an ion. In the derivation of the expected phase shif…

Focusing characteristics of a 4 parabolic mirror light-matter interface
Lucas Alber, Martin Fischer, Marianne Bader +3
Focusing with a 4 parabolic mirror allows for concentrating light from nearly the complete solid angle, whereas focusing with a single microscope objective limits the angle cone…
