Posted on 02/09/2010 12:26:12 AM PST by ErnstStavroBlofeld
Air Force Office of Scientific Research and National Science Foundation-funded professor, Dr. Xiang Zhang has demonstrated at the University of California, Berkeley the world's smallest semiconductor laser, which may have applications to the Air Force in communications, computing and bio-hazard detection. The semiconductor, called a plasmon, can focus light the size of a single protein in a space that is smaller than half its wavelength while maintaining laser-like qualities that allow it to not dissipate over time.
"Proposed almost seven years ago, researchers had been unable to demonstrate a working plasmonic laser until our experiment," said Zhang. "It is an important discovery because it has the potential to eliminate optical loss and make plasmonic-based technologies viable for a broad spectrum of applications."
"Perhaps the biggest gap in our knowledge and the reason it took so long to demonstrate this technology was our challenge of devising a realistic plasmonic laser design," he said. "We developed a strategy to get around this problem by combining semi-conductor nanowires one-thousand times thinner than a human hair with a metal surface separated by an insulating gap of only five nanometers, the size of a single protein molecule."
Because of their ultra small size, Zhang admits that an even more challenging aspect of his research has been in demonstrating how the plasmonic lasers bridge electronics, optics and photonics on the nanometer scale

You know, I have one simple request. And that is to have sharks with frickin’ laser beams attached to their heads! Now evidently my cycloptic colleague informs me that that cannot be done. Ah, would you remind me what I pay you people for, honestly? Throw me a bone here! What do we have?
Apparently journalistic incompetence afflicts even the Air Force Office of Scientific Research.
I dont think so. I think that they can do that with a laser.
...and Zing Zang has appropriately communicated his findings to his masters in the homeland, who see many wonderful military applications for use against the American imperialists....
The United States Air Force has a scientist working on laser technology and his name is Xiang Zhang?
The Chinese military will not have to fight our military.
THEY ALREADY HAVE TAKEN OUR MILITARY FROM THE INSIDE.
We are not just funding Chinese military research. We are bringing the bastards over here and giving them the run of the place with our blessings and full funding.
I just read a story on this web site yesterday in which a Chinese scientist was sentenced to many years in prison by a U.S. federal judge for stealing military secrets here and passing them to his government in China.
The United States does not deserve to continue as a nation if our military is this stupid about our military secrets.
For some odd reason I have these images of a micro miniature Racquel Welch in my body with a phaser killing evil terrorist cells.
This is outstanding good news for the nanotech medical field of inside the body corrective surgery, programmed nanaobots injected by a doctor could have cutting tools to surgically repair blood clots, dissolve material in blocked arteries, well its just amazing to look at this from just the medical POV.
Another thought about this is using devices like this as an offensive weapon such as a “bomb” that infects the enemies equipment from within, it attacks electronics disabling them, destroys critical components like firing systems.
Little miniature robots with frickin lasers....
And they are gonna kill us all due to the incompetence of our gov't, who think it is perfectly acceptable to employ foreigners from an enemy country on a project with deep national security implications.
Now they gotta find some really, really small sharks, or maybe micro-sized mutated sea bass. Thanks sonofstrangelove.
small as a protein?
The research was funded by some guy named Atkins.
