Journal ArticleDOI
Quantum cascade lasers: a versatile source for precise measurements in the mid/far-infrared range
TL;DR: In this article, the authors provide an overview of recent developments of quantum cascade lasers (QCLs), from the mid-infrared (mid-IR) to the far-IR (THz) range, with a special focus on their metrological-grade applications in a number of fields.
Journal ArticleDOI
Probing the Ultimate Limit of Fiber-Optic Strain Sensing
TL;DR: Strain measurements are reported at the 10−13ε-Hz–1/2 level using a fiber Bragg-grating resonator with a diode-laser source that is stabilized against a quartz-disciplined optical frequency comb, thus approaching detection limits set by thermodynamic phase fluctuations in the fiber.
Journal ArticleDOI
Molecular gas sensing below parts per trillion: radiocarbon-dioxide optical detection.
Iacopo Galli,Saverio Bartalini,Simone Borri,Pablo Cancio,Davide Mazzotti,P. De Natale,Giovanni Giusfredi +6 more
TL;DR: The ultimate sensitivity limits of molecular trace gas sensing are pushed down to attobar pressures using a comb-assisted absorption spectroscopy setup, and this result represents the lowest pressure ever detected for a gas of simple molecules.
Journal ArticleDOI
Observing the intrinsic linewidth of a quantum-cascade laser: beyond the Schawlow-Townes limit.
Saverio Bartalini,Simone Borri,Pablo Cancio,Antonio Castrillo,Iacopo Galli,Giovanni Giusfredi,Davide Mazzotti,Livio Gianfrani,P. De Natale +8 more
TL;DR: A comprehensive investigation of the frequency-noise spectral density of a free-running midinfrared quantum-cascade laser is presented, providing direct evidence of the leveling of this noise down to a white- noise plateau, corresponding to an intrinsic linewidth of a few hundred hertz.
Journal ArticleDOI

TL;DR: The Search for Anomalous Gravitation using Atomic Sensors (SAGAS) project as mentioned in this paper aims at flying highly sensitive atomic sensors (optical clock, cold atom accelerometer, optical link) on a solar system escape trajectory in the 2020 to 2030 time-frame.
