Laser in section. How I searched for potassium titanyl phosphate and barium beta-borate among aluminum sawdust

“Do you know what's inside the drum?” Is the end of a sad joke

"Yes, even drown it in acid" shop laser pointers green-laser.ru

Recently, a Jedi blue sword, a laser pointer of "normal" power, fell into my hands. I will say this, that the laser beam is clearly visible on a sunny day, if you look at the beam in the evening, then your eyes ache for two hours, and when you turn on the laser in the room, the reflected light and the spot on the wall are so bright that they immediately blind the eyes.
Having burst the balls and pozazhigav matches, I wanted more, so I decided to send greetings to the pilots to help our football team "turn into a radioactive ash" the neighboring cat to see what is inside this wonderful device.



Attention, under the cut scenes of gadget abuse

Laser parsing

The laser consists of a rather massive case, heaps of radiators and a diode driver card. Eats 1 large or 2 small batteries (charger included)


To me, this thing reminds me of a bug from the "Matrix"?

Glasses

The glasses are at first glance flimsy and not credible, but if you put them on, the laser beam is not at all visible.
My first hypothesis was that the laser would perforate them instantly. It was not there.
After two minutes of emission by a laser perpendicular to the plane of the lens, its surface was not even heated.

Cut in Russian

“There are no user serviceable parts inside.” V. Vinge, “End of the Rainbow”
"... a needle in an egg, an egg in a duck, a duck in a hare, a hare in a chest ..." a fairy tale

And what about inside the blue?



Inspired by foreign experience, I bravely took up the saw.


Hands a little crooked


Two halves of aluminum radiator


Copper radiator ( UPD as written in the comments - from brass)


Interestingly, when cutting aluminum radiator, it was very hot (it burned fingers), and the copper one remained cool, although I sawed it more intensively


Dopili copper radiator ( UPD as written in the comments - from brass)


Oops come. This small part, which turned out to be at the end of the wires, I couldn’t even take a good picture on my lens. And this is what planes are shot down by blinded !? I was expecting (as with foreign sawfinders) to see crystals and non-linear optical elements, a system of translucent mirrors, to see indium-gallium nitride (In _x Ga _1-x N) or barium borate (BaB ₂ O ₄ ) ... In general, me, Like the hero of the novel Vernor Vinge, there was a slight disappointment - “there are no user-serviceable parts inside” - but the process itself was interesting.

How to use such powerful pointers

(bright side):
As I found out, these lasers are often taken by hunters and fishermen to brush off tigers and bears, since the young animals are also not very pleased to look at the blue ray. Plus, the beam is perfectly visible at a distance and helps out if you get lost. One friend bought such a pointer and used it as a portable laser engraver to mark the work tool in production. Pointers use gardeners in the household, as a level, for example. There are several examples of using laser pointers for security systems and perimeter control.

Thanks

I express my gratitude to the company green-laser.ru for providing the laser for anti / pseudo / pseudo about scientific experiments, as well as to Ivan and Serezha from the “Laboratory of three-dimensional printing” for the vice and the hacksaw for metal

P.S.

Who knows what to do with what is left of the laser (for example, to cut further), welcome to Hackspace.
