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 ...

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.

Abstract: Compact homodyne laser diode interferometers (HLDIs) can not only be applied as an instrument for off-machine measurement, but also be integrated into an equipment as a sensor for on-machine ...
