Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

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 ...

Carbon monoxide (CO) lasers have long been a subject of interest owing to their capacity to operate in the mid-infrared spectral region, which is vital for applications ranging from remote sensing to ...

The search for rocky, Earth-like exoplanets has received a boost, with the arrival of a new laser frequency comb at the European Southern Observatory’s La Silla Observatory in Chile. Built by a team ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

Scientists from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t let its size fool you. This tiny laser could power the next generation of ...

The figure shows the Brillouin-gain-spectrum map obtained along a 13-m single-mode silica fiber. The upper diagram marks a ~1.1-m strained section. The lower color plot displays the corresponding ...

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the ...

Recently, the research team led by Prof. ZHANG Tianshu at the Anhui Institute of Optics and Fine Mechanics, the Hefei Institutes of Physical Science of the Chinese Academy of Science developed a ...
