Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the ...

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 ...

Attosecond pulses enable sub-femtosecond studies of ultrafast electron dynamics. Since 2001, pulse durations have shortened ...

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 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 ...

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 ...

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 ...

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 ...
