Technical University of Denmark (DTU) researchers achieve 43Tbps using a single laser
Between 2009 and 2011, the Technical University of Denmark (DTU) was on a record-breaking binge. It all began with DTU breaking the 1Tbps (terabits per second) fiber-optic data transmission barrier using a single laser in March 2009, only for researchers at the Danish institute to outdo themselves over the next two years with yet more impressive efforts of 5.1Tbps and 9.5Tbps, respectively. Their dominance ended in 2011, though, when Germany’s Karlsruhe Institute of Technology took the record away from them.
What's even cooler than a kick-ass high-speed wireless network? A kick-ass high-speed wireless network powered by frickin' lasers. It may just lay in our future: researchers from the National Taipei University of Technology managed to create a rudimentary, working 1Gbps network that bypasses radio frequencies entirely, using basic AAA battery-powered red and green laser pointerss and about $600 worth of components. That's waaaaay faster than the 802.11n Wi-Fi routers found in homes today.
We’re sorry, but if you can view the brilliant green beam of the Wicked Lasers Krypton without going gaga with geeky excitement, then we have to question whether you have a soul inside. It’s a laser, people! It’s a handheld green laser that shines more brilliantly and fan-bloody-tastically than anything else you may ever point into the night’s sky.
Here's the deal, you shouldn't ever look at a laser beam head on, especially one built by Wicked Lasers. It's all fun and games until someone goes blind, and that's exactly what will happen if you try and stare directly at the 1W laser dot in the company's new Spyder 3 Krypton. Wicked Lasers says the device is under review by the Guinness World records as the world's brightest handheld laser in the world, and considering it can be seen from space, we have a feeling it will be a short review.
There's no way around it; you're going to look awfully dorky wearing Apira Science's hands-free iGrow laser hair rejuvenation system. But if you can tough it out for 12-24 weeks, you'll have thicker, fuller, healthier hair, Apira claims. iGrow uses a patent pending combination of built-in laser and LED lights that works on both men and women and supposedly uses the same low level laser therapy technology found in the Revage670.
Officially, it's called the Assault Intervention Device, and what it does is fire off a focused, non-lethal beam of energy at the target, which in this case will be inmates trading blows with each other. But even though it's not a deadly laser, prison officers describe the sensation as "excruciatingly painful."
"We hope that this type of technology will either cause an inmate to stop an assault or lessen the severity of an assault by them being distracted by the pain as a result of the beam," said Bob Osborne, Commander of the Sheriff's Department of Technology Exploration Program. "I equate it to opening an oven door and feeling that blast of hot air, except instead of being all over me, it's more focused.
"And you begin to feel this warming feeling, and then you go 'Yow, I need to get out of the way,'" Osborne added.
Plans are in place to mount the device on the ceiling at Pitches Detention Center at Los Angeles County Jail, home to some 65 convicts.
"This device will allow us to quickly intervene without having to enter the area and without incapacitating or injuring either combatant," said Sheriff Lee Baca in a statement.
While we sit and wait for downloadable and streaming content to fully replace optical media, Sony, with the help of some talented folk at Tohoku University, is already working on the next iteration of Blu-ray. Those involved say that by harnessing a blue-violet laser, a disc could come crammed with up to 50 full-length movies or an entire TV series.
"This latest successful development is an all-semiconductor laser picosecond pulse source with a laser wavelength of 405 nanometers (1nm = one billionth of a meter) in the blue-violet region," Sony explains. "It is capable of generating optical pulses in the ultra-fast duration of 3 picoseconds (1 picosecond = one-trillionth of a second), with ultra-high output peak power of 100 watts and repetition frequency of 1GHz."
We love it when companies talk all geeky to us, and there's plenty of nerd-speak in the full press release. Put into plain English, this latest blue-violet laser is more than a hundred times stronger than the world's highest output value for conventional blue-violet, and barring any setbacks, will succeed the current Blu-ray format in the coming years.
It was on May 16, 1960 that Huges Lab researcher Theodore Maiman built the world's first laser using a flash lamp to simulate a pink ruby rod. Now 50 years later, lasers have become a prominent fixture in every day life. Here's a quick look at some of the lasers hits and misses.
Back before Val Kilmer largely fell off the acting radar, he starred in a movie called Real Genius as a laid back college student working on a chemical laser. In the final seen, Kilmer and fellow students fill their corrupt professor's house with a huge tin of popcorn and pop it using a laser, which fills the entire home. Sure, Mythbusters went on to debunk the possibility of something like this happening in real life, but the original scene is no less awesome, or memorable. Watch the clip here.
Anyone remember Kenwood's 72X TrueX optical drive? We do, and we named it one of the top 10 tech blunders because of its high failure rate, disappointing speeds, and poor media compatibility. The technology seemed promising at the time, which took a normal red laser diode and sent it through a diffraction grating splitting it into seven parts, but the technology just couldn't live up to the hype.
In late 2008, Microsoft took blue lasers mainstream with its Sidewinder X8 mouse. Our verdict? A disappointing 5. Read the review here.
So we weren't overly impressed with Microsoft's X8, but we absolutely loved (and still do) Logitech's G9x, the only rodent we've ever awarded with a perfect 10 verdict. The G9x replaces the original G9's 3,200dpi laser sensor with a 5,000dpi laser senor, resulting in ultra-sensitive movement when you need it. Read the review here.
So where lasers go from here? Time will only tell, but here's to another 50 years of awesome innovation (and wacky Hollywood portrayals).
In this age of online documents, sometimes you still need a fast printer that kills trees. If you’re a small legal office, print large preview documents for clients or need high capacity archival printing, a fast laser printer with capacious paper trays is still incredibly useful. Toss in fax and scanning capabilities, plus network connectivity and an affordable price, and the Lexmark X264dn seems to offer all the ingredients for a killer all-in-one device for small workgroups that don’t need color.
Microvision on Monday unveiled its Web store for U.S. customers for the SHOWWX laser pico projector, and plans to fully cut the ribbon later this month. According to Microvision, this is the world's first laser pico projector based on the company's PicoP technology in the U.S.
The company will offer two products when the store opens, including the Standard Edition SHOWWX and the Limited Edition SHOWWX promotional bundle. Both versions sport a native resolution of 848 x 480 (WVGA), plug-and-play use, "fiddle-free" infinite focus, a 5,000:1 contrast ration, a 60Hz refresh rate, 3.5mm stereo jack, and about 90-120 minutes of battery life when fully charged.
So what makes the Limited Edition different?
"The Limited Edition SHOWWX bundle is for the technology enthusiast and ultra-mobile media connoisseur," Microvision explains. "This special bundle comes with a personalized splash screen bearing the name of its owner, SHOWWX with 'Limited Edition' insignia, certificate of authenticity and a SHOWWX VGA dock plus other accessories not included with the Standard Edition."
The Limited Edition is available now for $1,000, while the Standard Edition will be made available on March 24 for $550.
