Researchers generate terahertz laser with laughing gas

[ArcticDude]

Within the electromagnetic middle ground between microwaves and visible light lies terahertz radiation, and the promise of "T-ray vision."

Terahertz waves have frequencies higher than microwaves and lower than infrared and visible light. Where optical light is blocked by most materials, terahertz waves can pass straight through, similar to microwaves. If they were fashioned into lasers, terahertz waves might enable "T-ray vision," with the ability to see through clothing, book covers, and other thin materials. Such technology could produce crisp, higher-resolution images than microwaves, and be far safer than X-rays.

That was an enjoyable read. Thanks, Tero. It seems they have also used CO and NH3 molecules to get similar results.

The original Masers were ammonia based. I will have to read that article.

This report also caught my eye when browsing the Nov 15 issue, very cool indeed. Also interesting is the collaboration between Harvard, MIT, and the people at Redstone Arsenal - which isnt too far from me in AL.

Have had the paper sitting on my desktop; meant to share but time got the best of me. I attached it for anyone interested!

Right, cant say I didnt reference google a few times myself. The chemistry & mechanics are straightforward, its the quantum stuff that gets you. At least its light on math!

That has a remarkably narrow line width. Far sharper than I thought it would be. Can't say I've ever run into carbonyl sulfide anywhere else.

Why wouldn't it be ?
