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.

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 ...

The new laser power detector HP60A-15KW-GD-QBH is ideal for those in need to measure average laser power for burn-in tests, during long periods of time or even quickly in the field with the simplicity ...

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 ...

Laser power measurement may look simple, but fascinating physics is working behind the scenes. Discover the insights behind ...

A research team has demonstrated a quantum-inspired laser rangefinder that measures distances with sub-millimetre accuracy across a city-scale gap, using only tens of microwatts of optical power.

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 ...
