Search for oscillations of fundamental constants using molecular spectroscopy
R. Oswald, A. Nevsky, V. Vogt +8
A possible implication of an ultralight dark matter (UDM) field interacting wibeginth the Standard Model (SM) degrees of freedom is oscillations of fundamental constants. Here, we…
Characteristics of long-lived persistent spectral holes in at
René Oswald, Michael Hansen, Eugen Wiens +2
Properties of persistent spectral holes (SHs) relevant for frequency metrology have been investigated in the system (0.5%) at crystallographic site 1 and a t…
Resonator with ultra-high length stability as a probe for Equivalence-Principle-violating physics
E. Wiens, A. Yu. Nevsky, S. Schiller
In order to investigate the long-term dimensional stability of matter, we have operated an optical resonator fabricated from crystalline silicon at 1.5K continuously for over o…
A compact, robust, and transportable ultra-stable laser with a fractional frequency instability of
Qun-Feng Chen, Alexander Nevsky, Marco Cardace +5
We present a compact and robust transportable ultra-stable laser system with minimum fractional frequency instability of at integration times between 1 to 10 s. T…
A silicon single-crystal cryogenic optical resonator
Eugen Wiens, Qun-Feng Chen, Ingo Ernsting +4
We report on the demonstration and characterization of a silicon optical resonator for laser frequency stabilization, operating in the deep cryogenic regime at temperatures as low…
Robust frequency stabilization of multiple spectroscopy lasers with large and tunable offset frequencies
Alexander Nevsky, Soroosh Alighanbari, Qun-Feng Chen +7
We demonstrate a compact and robust device for simultaneous absolute frequency stabilization of three diode lasers whose carrier frequencies can be chosen freely relative to the re…
