Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

Scientists directly measured the lithium left behind in the mesosphere when pieces of a SpaceX rocket fell to Earth over ...

Following its recent launch of integrating sphere laser power detector series, Gentec-EO now adds another model of fast laser power detectors, the IS50A-1KW-RSI. Probably the most remarkable feature ...

Accurately measuring the power in a laser beam is a difficult proposition. There are nearly as many different kinds of meters as there are lasers, and none of them are cheap. If you tried to use a ...

Measuring conditions in volatile clouds of superheated gases known as plasmas is central to pursuing greater scientific ...

Always on the lookout for better ways to measure all kinds of things, researchers have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the ...

Miranda van Iersel, an assistant professor in New Mexico State University's Klipsch School of Electrical and Computer Engineering, has been selected as a recipient of the 2025 Gentec-EO Laser Lab ...
