As the city of Oak Ridge races to once again be the U.S. capital of uranium enrichment, one company hopes to commercialize a ...

The researchers realized that the molten pools needed to be stabilized, which they could do by applying a shielding gas or ...

MAGA are convinced Donald Trump's Arizona rally was attacked by chemical gas and laser weapon after some attendees started ...

A third option is to frequency-double a gas laser to shift its output wavelength from around 10 μm to 5 μm. “Quantum cascade lasers can generate milliwatt continuous powers or multiwatt peak ...

Rather, he built a very clever gas mixer for filling his homemade CO2 laser tubes, which only looks like a welding machine. (Video, embedded below.) We’ve been following [Lucas] on his journey ...

As these laser pulses travel through the atmosphere ... That trade-off, however, allowed the researchers to detect molecules of gas with a lot fewer errors than before. They tested the approach ...

To achieve fast detection of low gas concentrations, the researchers combined a laser with an extremely fast tunable wavelength with quartz-enhanced photoacoustic spectroscopy and integrated ...

To detect low gas concentrations quickly, however, requires not only a laser that can be tuned rapidly but also an extremely sensitive detection mechanism and precise electronic control of the ...

In many cases they've replaced older technologies, such as gas lasers, because their improved ... The typical high-power ion laser of five years ago had a mean time-to-failure of about 2,000 ...

For example, a plume expanding into ambient gas of low pressure around 100 mTorr exhibits plume splitting and sharpening [1]. A definitive mechanistic explanation for laser-induced plasma plume ...
