Construction techniques and commissioning of the Three-Backlink Experiment for the LISA mission
Lea Bischof, Melanie Ast, Jiang Ji Ho-Zhang +10
Designed to detect gravitational waves in the lower-frequency band, the space mission LISA will open a new window to astronomy after its launch in the 2030s. Each LISA spacecraft h…
Demonstrating sub-picometer non-reciprocity levels in the Three-Backlink Experiment for LISA
Jiang Ji Ho-Zhang, Melanie Ast, Lea Bischof +9
The current planned space-based gravitational-wave detectors require a bidirectional optical connection, referred to as Backlink, between two adjacent optical benches to provide a…
Single-Element Dual-Interferometer for Precision Inertial Sensing: Sub-picometer Structural Stability and Performance as a Reference for Laser Frequency Stabilization
Victor Huarcaya, Miguel Dovale Álvarez, Kohei Yamamoto +7
To reach sub-picometer sensitivity in the millihertz range, displacement sensors based on laser interferometry require suppression of laser-frequency noise by several orders of mag…
fractional laser frequency stability with a 7-cm unequal-arm Mach-Zehnder interferometer
Victor Huarcaya, Miguel Dovale Álvarez, Daniel Penkert +7
To achieve sub-picometer sensitivities in the millihertz band, laser interferometric inertial sensors rely on some form of reduction of the laser frequency noise, typically by lock…
Vanishing tilt-to-length coupling for a singular case in two-beam laser interferometers with Gaussian beams
Sönke Schuster, Gudrun Wanner, Michael Tröbs +1
The omnipresent tilt-to-length coupling in two-beam laser interferometers, frequently a nuisance in precision measurements, vanishes for the singular case of two beams with identic…
Analytical description of interference between two misaligned and mismatched complete Gaussian beams
Gudrun Wanner, Gerhard Heinzel
A typical application for laser interferometers is a precision measurement of length changes that result in interferometric phase shifts. Such phase changes are typically predicted…
