In this video, I demonstrate the process of laser cleaning aluminum using a 500-watt laser, focusing on the restoration of a ...

Lasers are pretty much magic — it’s all done with mirrors. Not every laser, of course, but in the 1980s, the most common lasers in commercial applications were probably the helium-neon … ...

“These high-performance mirrors represent an indispensable contribution to the realization of commercial laser fusion power plants in reliable continuous operation,” said Gönüllü. The research project ...

This mirror is a force scale that relates the force of a laser shining on it to the power (i.e., the brightness) of that laser. Scientists at NIST are developing these devices to embed into laser ...

The new project uses femtosecond laser micromachining to selectively remove regions of coating from the back surface of a mirror, after a map of the necessary stress correction has been calculated ...

This modular digital measurement system was built for pro-level accuracy - and it's super useful for hanging pictures ...

For long exposure times, the laser cleaning also restores the thermal emissivity better than the CO₂ snow. While a CO₂-snow delivery system can be less expensive than a UV-laser-cleaning system, the ...
