Researchers at NIST have upgraded their laser frequency-comb instrument to simultaneously measure three airborne greenhouse gases -- nitrous oxide, carbon dioxide and water vapor -- plus the major air ...
(Nanowerk News) Like many new measurement tools, the laser frequency comb seemed at first a curiosity but has found more practical uses than originally imagined. The technique for making ...
High-frequency combs have made possible some of the most advanced benchtop instrumentation available today (see for example, “Nonlinear VNA goes to 67 GHz,” edn ...
Astronomers searching for alien planets may be a step closer to finding true Earth-like worlds around sun-like stars, by using a new tool that promises to increase the accuracy of planet-hunting ...
Laser combs, in which the output is divided into a series of discrete frequency lines, are already valuable sources for gas sensing applications and the detection of different species. A project at ...
Promising new calibration tools, called laser frequency combs, could allow astronomers to take a major step in discovering and characterizing earthlike planets around other stars. These devices ...
An important technique for discovering and characterizing planets beyond our solar system relies upon measurement of weak Doppler shifts in the spectra of host stars induced by the influence of ...
Laser frequency combs are valuable analytical tools for observing chemical phenomena or detecting the presence of particular species at low concentrations. The key to these applications is the ...
