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 from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t let its size fool you. This tiny laser could power the next generation of ...

Hamamatsu Photonics is committed to supporting innovation in photonics and enabling practical solutions for real-world ...

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the ...

Lidar systems enable precise obstacle detection, distance measurement, and real-time mapping for safer interaction between ...

How innovations in visibility, usability, and smart sensing are changing who uses tools—and how. For centuries, measurement tools have been essential to architecture, engineering, construction, real ...

The Tata Institute of Fundamental Research, Mumbai has pioneered a method to measure ultrahigh power, ultrashort laser pulses in a comprehensive manner. The paper reporting this has just been ...

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 ...
