A transportable interrogation laser system with an instability of
Sebastian Häfner, Sofia Herbers, Stefan Vogt +2
We present an interrogation laser system for a transportable strontium lattice clock operating at 698 nm, which is based on an ultra-low-expansion glass reference cavity. Transport…
Geodesy and metrology with a transportable optical clock
Jacopo Grotti, Silvio Koller, Stefan Vogt +21
The advent of novel measurement instrumentation can lead to paradigm shifts in scientific research. Optical atomic clocks, due to their unprecedented stability and uncertainty, are…
A transportable optical lattice clock with uncertainty
S. B. Koller, J. Grotti, St. Vogt +5
We present a transportable optical clock (TOC) with Sr. Its complete characterization against a stationary lattice clock resulted in a systematic uncertainty of ${7.4 \times…
Development of a strontium optical lattice clock for the SOC mission on the ISS
S. Origlia, S. Schiller, M. S. Pramod +25
The ESA mission "Space Optical Clock" project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests…
8E-17 fractional laser frequency instability with a long room-temperature cavity
Sebastian Häfner, Stephan Falke, Christian Grebing +5
We present a laser system based on a 48 cm long optical glass resonator. The large size requires a sophisticated thermal control and optimized mounting design. A self balancing mou…
Development of a strontium optical lattice clock for the SOC mission on the ISS
K. Bongs, Y. Singh, L. Smith +24
Ultra-precise optical clocks in space will allow new studies in fundamental physics and astronomy. Within an European Space Agency (ESA) program, the Space Optical Clocks (SOC) pro…
A transportable strontium optical lattice clock
N. Poli, M. Schioppo, S. Vogt +4
We report on a transportable optical clock, based on laser-cooled strontium atoms trapped in an optical lattice. The experimental apparatus is composed of a compact source of ultra…
A strontium lattice clock with inaccuracy and its frequency
Stephan Falke, Nathan Lemke, Christian Grebing +10
We have measured the absolute frequency of the optical lattice clock based on Sr at PTB with an uncertainty of using two caesium fountain clocks. This i…
The 87-Sr optical frequency standard at PTB
St. Falke, H. Schnatz, J. S. R. Vellore Winfred +8
With 87-Sr atoms confined in a one dimensional optical lattice, the frequency of the optical clock transition 5s^2 ^1S_0 - 5s5p ^3P_0 has been determined to be 429 228 004 229 872.…
Demonstration of a Transportable 1 Hz-Linewidth Laser
Stefan Vogt, Christian Lisdat, Thomas Legero +4
We present the setup and test of a transportable clock laser at 698 nm for a strontium lattice clock. A master-slave diode laser system is stabilized to a rigidly mounted optical r…
