SHE’LL stop at nothing in her quest for the perfect skin. Even if that means having a facial treatment so painful that some ...

In this week’s Science for All newsletter, Vasudevan Mukunth explains a new way to detect radioactive materials using ...

Physicists develop innovative technique using carbon-dioxide lasers to detect radioactive materials from safe distances for ...

Carbon dioxide lasers emitting at around 9.4 μm and 10.6 μm can also be frequency-doubled to reach wavelengths of around 5 μm. Operating at their fundamental wavelengths they are suitable for ...

Lasers in which the active medium consists of a low-pressure gas of carbon dioxide molecules have been used to produce the most powerful continuous laser beams achieved to date By C. K. N. Patel ...

So a research team led by Professor Howard Milchberg of the University of Maryland's Applied Physics Laboratory developed a method to detect radiation from long distances using a CO2 laser ...

Towed behind a tractor, the LaserWeeder is capable of killing up to 200,000 weeds per hour using an array of thirty 150W carbon dioxide lasers, operating at 10.6 um in the infrared range.

Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, ...

With the number of craftsmen dwindling, a physicist turned to an all-powerful carbon dioxide laser to facilitate the manufacturing and repair of Thailand’s most important art forms: chatras.
