Who among teenagers and most male adults doesn't dream of assembling their own laser sword? Laser pointers are out of fashion a long time ago, and their power is unlikely to impress anyone. However, this does not mean that they will not serve you in the end. A laser sword will not come out of them, but a completely powerful laser will turn out.
Instructions
To make a laser at home, you will need a laser pointer, a DVD drive with a working laser, a flashlight, wires and a soldering iron. You can buy a broken DVD on the radio market if there is no one on the farm.
In the first step, you need to remove the laser diode from the DVD. This is a long and painstaking process. When you open the DVD, you can easily find a carriage that moves along two guides. Unscrew the carriage carefully. You will have a lot of screws on your way, you need to remove them without haste, since the laser diode does not tolerate shaking and shock. When you remove it from the carriage body, hold it carefully and carefully.
The second stage is the replacement of its native diode in the laser pointer with the one removed from the drive. This is necessary to make the laser more powerful. The fact is that inside the pointer there is a low-power laser diode, while in a DVD the laser is a class higher. The laser pointer can be twisted into two parts. The diode is installed at the top. You need to get your own diode and emitter. After that, you need to install a diode from a DVD in the upper case. It is best to place it on an adhesive base.
In the third step, you need to place the refined top of the pointer into a flashlight with a suitable body. The upper part of the flashlight will serve as a replacement for the lens removed from the pointer. The power supply of the diode must be connected to the batteries of the flashlight, so you will power the laser. Remove the glass from the flashlight as it will get in the way of the laser beam.
Check that the laser is firmly installed, the polarity and power connections, the presence of batteries and the tightness of the fastening parts of the flashlight. Now everything is ready and your laser can light a match, burn through plastic or paper.
Remember, such a laser is a real threat to human health. Therefore, be careful and careful.
