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 ...

A gas laser in which a very short electrical pulse excites a mixture containing a halogen such as fluorine and a rare gas such as argon or krypton. It produces a brief, intense pulse of ...

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 ...

Laser-plasma accelerators can accelerate particles over distances that are up to 1,000 times shorter than those required by ...

Atop the fuselage, the Active Ranging System, a modified electronic targeting pod like those used by fighter airplanes, would acquire the missile and track it with a high-power gas laser to ...

The laser chamber contains a gas mixture of argon and fluorine and a buffer gas like neon. When high-voltage electrical pulses are applied, the argon and fluorine atoms become excited and briefly ...

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 ...

Other sources, with narrower emission and higher brightness, are gas lasers (for example CO 2 lasers) and lead-salt lasers. Both these types of laser have high power consumption and require cooling.

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.

Safran led an investment round into French startup mirSense, a laser design specialist, raising 7 million euros ($7.9 million) in total.

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 ...
