| The latest issue of "New Scientist" magazine, researchers at Yale University have developed a method based on semiconductor silicon, can fully absorb the laser. Proof of their previous calculations,titanium dioxide, you can use a specific wavelength of the intrinsic coherence of material,magnesia supplier, to offset the incident laser, the technology is equivalent to "anti-laser."
HuiCao Yale University research team led by 110 microns wide with a piece of silicon plate made such an "anti-laser", also known as "the perfect absorption of coherent light modulator" (coherent perfect absorber). By adjusting the specific optical phase, they found that the incident beam will miraculously change "black", the test showed that the silicon is almost eliminated all the range of 945 nm wavelength of light. "Anti-laser," in theory, 99.999% of the incident light can be absorbed. This sets the current proof of concept prototype, can absorb 99.4% of the near-infrared light and the light energy into heat energy. The researchers believe that by adjusting the electronic properties of materials and media parameters, the device can absorb visible light transmission and communication fiber specific frequencies of light. This finding is the wide range of possible applications,optical coating exporter, including a more realistic "light switch", it can be whimsical space laser defense system, which will based on "laser" and "Star Wars" program to nothing. Interestingly, the laser weapon system has not yet been put into practical, "anti-laser" theory and experiment has been one step ahead. Source: http://www.mhcocm.com |

Cory blushed, craned his neck cheap newport cigarettes, and gazed up at the stars. In a gruff, hesitant voice he said newport cigarettes wholesale, "I'm not a real cowboy." "No?" She let her gaze slide over his body, from the tip of his pointy, dusty cowboy boots, to his Texas tie. Languidly newport cigarettes wholesale, she asked, "What are you then?" "A venture capitalist from Chicago." He cocked a half grin at her. "I thought I'd come here to find a good old fashioned country girl." The irony caught her off guard and she chuckled. "I'm from New York City. I wanted a good old fashioned country boy." His gaze turned serious as he hauled her back against him. "Too late. . . . I'm staking my claim and I'll fight any of those cowboys that come near you." "Ditto newport menthol cigarettes, Sir. I didn't really fancy living on the range with a lot of smelly cows anyway." She rubbed her aching behind and admitted wholesale marlboro cigarettes, "And I don't ever want to ride that darn mechanical bull again as long as I live!" Cory laughed. "Done. How about we hold any more talk till morning?" He nibbled her neck as his hands caressed her heated flesh. All thought fled. Brazen Elaine Hopper Yes Newport 100s cigarettes," Tracy said. "You and Charles really haven't known each other long, have you?" Mrs. Stanhope asked. Tracy fought back her resentment. I was right. It is going to be an inquisition. "Long enough to know that we love each other, Mrs. Stanhope." "Love?" Mr. Stanhope murmured. Mrs. Stanhope said discount newport cigarettes, "To be quite blunt newport 100 cigarettes, Miss Whitney cheap newport cigarettes 02, Charles's news came as something of a shock to his father and me." She smiled forebearingly. "Of course, Charles has told you about Charlotte?" She saw the expression on Tracy's face. "I see. Well., he and Charlotte grew up together. They were always very close, and--- well, frankly, everyone expected them to announce their engagement this year." It was not necessary for her to describe Charlotte. Tracy could have drawn a picture of her. Lived next door. Rich marlboro cigarettes wholesale, with the same social background as Charles. All the best schools. Loved horses and won cups. "Tell us about your family," Mr. Stanhope suggested. My God, this is a scene from a late-night movie, Tracy thought wildly. I'm the Rita Hayworth character usa made cigarettes, meeting Cary Grant's parents for the first time. I need a drink. In the old movies the butler always came to the rescue with a tray of drinks. "Where were you born marlboro cigarettes 12, my dear?" Mrs. Stanhope asked. "In Louisiana. My father was a mechanic." There had been no need to add that, but Tracy was unable to resist. To hell with them. She was proud of her father. "A mechanic?" "Yes. He started a small manufacturing plant in New Orleans and built it up into a fairly large company in its field. When father died five years ago cheap marlboro cigarettes 03, my mother took over the business" |
