NIST researchers have developed a compact, high-accuracy, point-of-use high-power laser power meter in the form of a folding mirror called “Smart Mirror,” making in-situ, real-time measurement of ...

A simple explanation of how a laser power meter works, showing how it measures light energy output using sensors and ...

Seattle-area startup says its technology could be used for orbital tracking and communication as well as for beamed power.

Fig 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...

Imagine walking into an airport or grocery store and your smartphone automatically starts charging. This could be a reality one day, thanks to a new wireless laser charging system that overcomes some ...

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 ...

Researchers have developed a smaller, faster and more sensitive laser power meter in the form of a folding mirror they call a 'smart mirror.' High-power lasers are now widely used in additive ...
