Laser sectional. As I was looking titanyl phosphate, potassium and beta-barium borate of aluminum shavings
«Did you know that the inside of the drum?» I> the end of a sad joke blockquote> I recently fell into the hands of the Jedi sword blue laser pointer "normal" capacity. Let's just say that the laser beam is clearly visible on a sunny day, if you look at the beam in the evening, then two hours later my eyes ache a bit, and when the laser is in the room, and the reflected light spot on the wall is so bright that immediately dazzle the eye.
Burst balloons and pozazhigat matches, I wanted more, so I decided to say hello to pilotampomoch our football team "to turn into radioactive ash" the neighbor's cat to see what's inside of this wonderful device.

Lasers in parsing h4> The laser consists of a rather massive body pile of radiators and board driver diode. Feeds 1 large or 2 small batteries (charger comes)
I am one that thing reminds bug from "The Matrix»?
Points h4> Points at first glance hlipenkie and not credible, but if you put them on, the laser beam can not be seen.
My first hypothesis was that the laser holing them instantly. Not a bit of it.
After two minutes, the laser emission is perpendicular to the plane of the surface of the lens is not even warmed up.

How to use such powerful pointers h4>
(Light side):
As I found out, these lasers often take hunters and anglers to keep off the tigers and bears, as young animals is not very nice to look at the blue ray. Plus, the beam is clearly visible at a distance and helps you lose. One friend bought a pointer and used it as a portable laser engraver to mark the working tool in the workplace. Pointer vacationers in the economy, as the level, for example. There are several examples of the use of laser pointers for security and perimeter control.
