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 ...

The group has developed a new laser-based device that can take any sample of gas and identify a huge variety of the molecules within it. It is sensitive enough to detect those molecules at minute ...

Get Instant Summarized Text (Gist) A new laser-based device can analyze gas samples to identify a wide range of molecules at concentrations as low as parts per trillion. The technology, based on ...

What’s that smell? If you can’t tell, maybe a new laser system from CU Bolder and NIST can help. The device is simple and sensitive enough to detect gasses at concentrations down to ...

CALGARY, AB / ACCESS Newswire / February 26, 2025 / DAYY Photonics Corporation, a leader in the photonics industry, has ...

All of the uranium in the bomb dropped on Hiroshima was enriched in Oak Ridge, including at the K-25 gaseous diffusion plant, ...

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to understand.

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 ...
