A revolutionary kind of laser light called an optical frequency comb makes possible a more precise type of atomic clock and many other applications ...

Spectroscopy that combines the accuracy of a frequency comb with the ease of use of a tunable, external cavity diode laser is demonstrated, enabling precise dispersion measurements of ...

That means the laser’s light is very pure and stable, which is important for making exact measurements. It can adjust across a frequency range of 24 gigahertz without skipping over any frequencies.

A special laser system has been developed, using two slightly different frequency combs. This allows for chemical analysis on tiny spaces -- it is a millimeter-format chemistry lab. With this new ...

It is a very special kind of light, which can be used for important measurements: so-called frequency combs play a major role in laser research today. While the light of an ordinary laser only has ...

Laser-based measurement techniques, known as optical metrology, can be used to study the physical properties of objects and materials. But current optical metrology requires bulky and expensive ...

Lidar, which measures how long it takes for pulses of laser light to bounce off surfaces and return, has been used in topographic mapping for decades, and now it has a very timely function.

For the first time, researchers have executed a three-dimensional survey of the world's biggest trees, using laser technology to precisely measure the volume and biomass of Northern Californian ...
