For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

Dual-comb spectroscopy (DCS) has rapidly become a cornerstone of precision molecular detection, offering unparalleled resolution, broad spectral coverage, and fast acquisition speed. From fundamental ...

A single-fiber linear-cavity laser integrated with multifunctional devices was proposed and demonstrated for fiber dual-comb acquisition speed enhancement. This setup enabled flexible control of the ...

Pressure measurement applications may require simultaneously measuring differential and gauge pressure, often employing two separate sensors with different reference points. However, this solution is ...

Freeform dual comb spectroscopy creates images of methane plumes not visible to the human eye. Dual comb advance: Esther Baumann works in the lab at NIST. Scientists at the U.S. National Institute of ...

Scientists use devices known as frequency comb lasers to search for methane in the air above oil and gas operations and to screen for signs of infection in human breath. A new study could help make ...

The trick to creating a better quantum sensor? Just give it a little squeeze. For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing ...
