Blu-ray Laser Gadget
i4u writes, "Wicked Lasers has done the unthinkable. They took the sparse blue laser diodes used in Blu-ray Disc drives and are making cool laser gadgets out of them, called Sonar. You can own one of these very limited edition lasers for $1,999.99. The price is that high because Wicked Lasers buys Blu-ray Disc players and removes the Blu-ray diode for the Sonar laser."
Can someone explain the importance of a blue laser over a regular handheld red laser of the same power that sells for ~$20?
It's blue.
