Keeping things fresh therefore requires rolling your own lasers, and these DIY nitrogen TEA and dye lasers seem like a fun way to go. These devices are the work of [Les Wright], who takes us on a ...

Like all lasers, nitrogen lasers typically consist of three basic parts: an energy source (or pump), a laser medium (also known as a gain medium), and an optical resonator. As in most gas lasers, the ...

Moreover, few studies have been dedicated to the reproduction of the air laser profile from nitrogen molecules propagating in the filament plasma based on the numerical simulation method. In this ...

THIS communication reports the experimental observation of optical Raman scattering from oxygen and nitrogen in the atmosphere using a pulsed nitrogen ultraviolet laser 1,2 as a light source.

First the researchers used a pulsing laser to zap the air and make plasma, which can best be understood as highly-activated air. Using this process, they were able to turn the abundant nitrogen ...

The only other prisoner to be executed by nitrogen had a similar response. By Nicholas Bogel-Burroughs Alabama conducted the second execution in the United States using nitrogen gas on Thursday ...

The most comprehensive scientific review of the global nitrogen cycle has outlined 150 "win-win" measures to significantly reduce nitrogen pollution while saving billions in costs across a range ...

This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.

There were two options: lethal injection, the default method, which Alabama had been accused of botching in the prison's execution chamber; and nitrogen hypoxia, an experimental alternative that ...

Wang Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has successfully synthesized high-energy-density materials cubic gauche nitrogen (cg-N) at ...

A death row inmate has been executed using a novel method. Why have authorities in Alabama used nitrogen gas, and why is it controversial? Kenneth Eugene Smith was originally scheduled to be put ...
