1S-2S spectroscopy of trapped
singly-ionized helium
Overview of the He+
experiment (in preparation)

Above: principle of the
experimental setup for 1S-2S excitation
of He+

Under
construction!
You can find some
background on our Jobs / Positions
page.
Soon a more detailed description will
follow here as well of the He+
experiment. We are pursuing several
unconventional ideas to meet the
challenges of exciting a 2-photon
transition in the extreme
ultraviolet in a
single trapped He+ ion.
For this experiment we collaborate
with dr. Tanja Mehlstaeubler and
prof. Piet Schmidt of the PTB in
Germany for the ion trapping.

Ramsey-comb
spectroscopy in Xenon at 110 nm based
on high-harmonic generation
|
|
The setup for Ramsey-comb
excitation based on high-harmonic
generation. The left part contains the
high-harmonic generation, the right part
the xenon excitation chamber with all
the diagnistics (like a time-of-flight
mass spectrometer). In the middle is a
extreme ultraviolet refocusing telescope
based on toroidal mirrors.

Soon a
description will follow here of the
Ramsey-comb excitation experiment in
xenon, where we excited the 8S
transition at 110 nm with the
Ramsey-comb method combined with
High-harmonic generation, reaching an
unprecedented accuracy with HHG
light. |
