Nonlinear magnonics studies the nonlinear interaction between magnons and other
physical platforms (phonon, photon, qubit, spin texture) to generate novel magnon states for …

High-speed measurement confronts the extreme speed limit when the signal becomes
comparable to the noise level. In the context of broadband mid-infrared spectroscopy, state …

Mid-infrared (MIR) spectrometers are invaluable tools for molecular fingerprinting and hyper-
spectral imaging. Among the available spectroscopic approaches, GHz MIR dual-comb …

Optical frequency combs have enabled distinct advantages in broadband, high-resolution
spectroscopy and precision interferometry. However, quantum mechanics ultimately limits …

Single-cycle pulses with a deterministic carrier-envelope phase enable the study and control
of light–matter interactions at the sub-cycle timescale, as well as the efficient generation of …

Sensors for quantitative monitoring of greenhouse gases from high-emission facilities, such
as wastewater treatment and industrial plants, are becoming essential to enforce regulatory …

This Letter presents a 0.4–5.2-µm frequency comb from a compact laser. We designed an
integrated fiber device for a figure-9 laser and constructed an all-fiber laser system. The …
