Laser Pointer, from WarnLaser dot com

The Razor series is Warnlaser's new series of violet lasers. The power is supplied by two AAA batteries and uses the newest micro-electronics technology. It has the most unique color out of all our other products. Warnlaser engineers these laser's power up to 200mW. The Razor series uses a genuine Sony Blue-Ray diode. The beam has a rather unearthly glow, which makes it a very unique color. Compared to similar laser pointers from other companies, the special price of $379.99 cannot be beaten.

What sets the UV spectral region apart is the subtlety (and complexity) of the light-matter interactions indigenous to the realm. Here, where wavelengths range from 400 nm to somewhat below 200 nm, almost all but the smallest atoms and molecules absorb light, inducing changes-even if only very transiently-in their electronic structure. The associated increase in internal energy is usually sufficient to make, break, or rearrange chemical bonds (see Fig. 1) and to excite ionize (but rarely ionize) atoms. These processes are the very essence of chemistry.
