BOOST is a small satellite mission that aims for testing the foundations of Special Relativity by performing a Kennedy-Thorndike (KT) experiment. A potential boost dependence of the velocity of light will be measured by comparing a length reference (i.e. a highly stable optical resonator) with a molecular frequency reference. more...mehr...

A measurement setup for the characterization of high reflectivity laser mirrors was developed to demonstrate the possibility of a 'piston' correction in optical paths due to scanning actuated laser beams over surfaces of optical components. more...mehr...

Iodine Clock

Several future space missions require optical frequency references with stability in the 10-15 domain at long integration times. One of the most auspicious methods to obtain space compatibility in a relatively short time is a setup based on Doppler-free spectroscopy using molecular iodine. more...mehr...

The Space-Time Explorer and Quantum Equivalence Principle Space Test mission (STE-QUEST) was selected by ESA as one of four candidates for the M3 mission within the Cosmic Vision Program with launch in 2022. more...mehr...

laser interferometry

Over the last few years, a heterodyne interferometer was developed as a laboratory prototype for the optical readout of the LISA gravitational reference sensor. The current interferometer setup is realized using a glass ceramics baseplate made of Zerodur in combination with adhesive bonding technology for optical component integration. more...

Micro-Newton thrusters

We are performing an experimental feasibility study on down-scaling HEMP (High Efficiency Multistage Plasma) thrusters in order to gain a deeper understanding of the influence of design parameters and to test the possibility of a working µN HEMP thruster. more...

Thrust balance

We develop and realize a thrust balance for the characterizing, test and development of micro newton thrusters (see here). Right now, the first generation of the thrust balance was developed and integrated. First performance tests were performed. more...

CTE measurements

We develop a measurement system to investigate the coefficient of thermal expansion (CTE) of ultra stable samples. Low CTE materials are important for stable structures in space applications to enable precise measurements. more...
