Abstract: We report on the design and construction of a Mach-Zehnder Interferometer with an adjustable measuring arm aimed at quantifying the coherence lengths of lasers for use in undergraduate ...

Abstract: We present a deformable ultrafast fiber laser based on a delay-tunable Mach–Zehnder interferometer, which can generate pulses with adjustable durations spanning from 239 fs to 24.51 ps, as ...

In 2016, the first direct observation of gravitational waves was reported. The measurements by the LIGO detectors gave astronomers a new way to observe the Universe. Gudrun Wanner is at the Institute ...

Physicists have long suspected that spacetime itself may exhibit tiny, random fluctuations at the smallest scales, but translating these ideas into experimental tests has remained a major challenge.
