Good article explaining how laser teeth whitening works and how it may be helpful. Do you guys think it is worth the risk and price to whiten tooth using laser whitening?

A team of researchers at the University of Colorado at Boulder has developed a new technique to generate laser-like X-ray beams, removing a major obstacle in the decades-long quest to build a tabletop X-ray laser that could be used for biological and medical imaging.

A laser developed for military use is a few steps away from hitting a power threshold thought necessary to turn it into a battlefield weapon.The Solid State Heat Capacity Laser has achieved 67 kilowatts of average power in the laboratory. It could take only a further six to eight months to break the "magic" 100kW mark required.

A team from MIT, US, has managed to focus 15 laser beams into a 180 nm spot without using a lens. Known as "coherent superposition" the technique could be ideal x-ray, ultraviolet and infrared regions of the spectrum, where focusing with a lens can be difficult or even impossible.

How would you like to talk over a laser beam? In about 15 minutes you can set up your own laser communication system, using cheap laser pen pointers and a few parts from Radio Shack.
