Hasta La Gadget!

This being Shark Week and all, budding super villains may be interested in this 1.25W laser from WickedLasers. This monstrous slab of electronics sends out a beam powerful enough to pop multiple balloons and looks like a light saber. It would look great on your shark’s head.

The 1.25W version of the WickedLasers Spyder S3 costs $399.95 and require eye protection to operate.

If you’re tempted, please remember that these are not toys. We’ve reviewed a few of these things over the years and they’re some serious ordnance. I very nearly burned my cornea once because I was being a doofus. Practice safe lasing, kids.

Those damn furry spiders love to chase lasers too. Like cats. It’s ok, spider. Come on. I will let you hunt my laser. And then fry you with it. More »

The US Department of Energy’s SLAC accelerator lab already has a pretty useful X-ray laser — the Linac Coherent Light Source (LCLS). But, recent modifications to the device have scientists drooling over its new found potential. Using a thin wafer of diamond, the Stanford-run lab filtered the beam to a lone frequency, then amplified it in a process called “self-seeding.” That’s given the world’s most powerful X-ray laser even more punch by tossing out unneeded wavelengths which were reducing its intensity. The tweaks allow scientists across many fields to finesse and image matter at the atomic level, giving them more power to study and change it. According to the lab, researchers who came to observe the experiment from other X-ray laser facilities “were grinning from ear to ear” at the possibility of integrating the tech into their own labs. The SLAC team claims they could still add 10 times more punch to the LCLS with further optimization, putting the laser in a class by itself — X-ray-wise, anyway.

Lovin’ the bold look of those new Nikes? If you’re up to date on the athletic shoe scene, you may notice that sneaker designs can give way long before your soles do. A new decaling technique could enable you to “erase” labels and other artworks overnight without a trace, however, letting you change up your wardrobe without shelling out more cash. A prototype device, called Shader Printer, uses a laser to heat (at 50 degrees Celsius, 120 degrees Fahrenheit) a surface coated with a bi-stable color-changing material. When the laser reaches the “ink,” it creates a visible design, that can then be removed by leaving the object in a -10 degree Celsius (14 degree Fahrenheit) freezer overnight. The laser and freezer simply apply standard heat and cold, so you could theoretically add and remove designs using any source.

For the purposes of a SIGGRAPH demo, the team, which includes members from the Japan Science and Technology Agency and MIT, used a hair dryer to apply heat to a coated plastic doll in only a few seconds — that source doesn’t exactly offer the precision of a laser, but it works much more quickly. Then, they sprayed the surface with -50-degree Celsius (-58 Fahrenheit) compressed air, which burned off the rather sloppy pattern in a flash. There were much more attractive prints on hand as well, including an iPhone cover and a sneaker with the SIGGRAPH logo, along with a similar plastic doll with clearly defined eyes. We also had a chance to peek at the custom laser rig, which currently takes about 10 minutes to apply a small design, but could be much quicker in the future with a higher-powered laser on board. The hair dryer / canned air combo offers a much more efficient way of demoing the tech, however, as you’ll see in our hands-on video after the break.

A home alarm system will automatically call the police in the event of a break-in, but by the time officers arrive, the intruders may have already taken your valuables. So this laser security system serves as an additional visual deterrent that your home is as protected as the most secure government facility. More »
