I explained how the Peltier effect enables the laser power meter to function as a thermopile, converting heat from lasers ...

Researchers set a record by guiding light in 45-meter-long air wave-guides. It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But ...

Researchers at the US National Institute of Standards & Technology, NIST have developed a compact, high-accuracy, point-of-use high-power laser power meter in the form of a folding mirror. Called ...

The team set out to investigate “optical guiding”: a method of directing light through air, which could be used for long-range laser communication. Based on a 2014 study, they knew that this works ...

I disassembled the budget laser power meter, revealing its internal components, including the Peltier heat pump sensor and ...

[Andrew] got a little help from his friends to hack a laser distance meter. Using laser distance meters as sensors is one of the great quests of hackers – with good reason. Accurate distance readings ...

A single app now controls nearly 30 Huepar devices and unlocks point-to-point spatial measurement, guided layout, and annotated jobsite drawings — features once reserved for high-end professional ...

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that’s what happened in UMD’s Energy Research Facility, an unremarkable ...
