The laser is built with a diode from Casio's new mercury-free Green Slim projectors which ironically have a somewhat blue tint. The laser is rated at 1 watt of power and retails for a mere $200 USD.
And here's the best (or worst) part -- it can set people (or things) on fire. Apparently the laser is so high powered that shining it on fleshy parts will cause them to burst into flames. Of course it's equally capable of blinding people. The retailer warns:
Warning: Extremely dangerous is an understatement to the power of 1W of laser power. It will blind permanently and instantly and set fire quickly to skin and other body parts, use with extreme caution and only when using the included eye protection.
