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 ...

Optical cavities form the cornerstone of high-precision laser frequency stabilisation by confining light between mirrors to produce well-defined resonant modes. In these systems, the stability of the ...

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 ...

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 ...

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 ...

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 ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...

Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser ...

The development of an ammonium fluorooxoborate crystal marks a breakthrough in vacuum ultraviolet laser technology, promising ...
