How to make a laser at home: technology

Many know about the possibilities of laser technology and their benefits. They are used not only in industry, but also in cosmetology, medicine, life, art and other branches of human life. However, not everyone knows how to make a laser at home. But it can be built from improvised materials. This will require a non-working DVD drive, a lighter or a flashlight.

Before you make a laser at home, you need to collect all the necessary elements. First of all, you need to disassemble the DVD-drive. To do this, all the screws that hold the top and bottom cover of the device are removed. Then the main loop is disconnected and the board is unscrewed. Protection of diodes and optics should be hacked. The next step is to extract the diode, which is usually done using pliers. In order that static electricity does not damage the diode, its legs must be tied with wire. Take out the diode carefully, so as not to break the legs.

Next, before you make a laser at home, you need to make a driver for the laser, which is represented by a small circuit that regulates diode power. The fact is that if the power is set incorrectly, then the diode can quickly fail. As a power source you can use finger batteries or the battery from a mobile phone.

Before you make a laser at home, you need to take into account the fact that the burning effect is provided by optics. If it does not exist, the laser will simply shine. As optics, you can use a special lens from the same drive, from which the diode was taken. To correctly set the focus, you need to apply a laser pointer.

In order to build a conventional pocket laser, you can use a conventional lighter. However, before you make a laser from a cigarette lighter, you need to learn the technology of the structure. Lusha all buy a quality incendiary element. It should be disassembled, but the details should not be discarded, since they are still useful in the design. If the lighter has a gas, it must be released. Then the insides must be carved with a drill with special nozzles. Inside the case of the lighter there is a diode from the drive, several resistors, a switch and a battery. All the elements of the lighter need to be installed in their place, after which the button that used to light the flame will turn on the laser.

However, to build the device you can use not only a lighter, but a flashlight. Before you make a laser from a flashlight, you need to take a laser unit from the CD-drive. In principle, the structure of a homemade laser in a flashlight does not differ from a laser device in a cigarette lighter. We need only take into account the power supply, which almost never exceeds 3 V, and it is also desirable to build an additional voltage regulator. It will extend the life of the laser. It is very important to take into account the polarity of the diode and the stabilizer.

All the collected stuffing should be placed in the body of the disassembled flashlight. Previously, not only the inner part, but also the glass is extracted from the flashlight. After installing the laser unit, the glass is put in place.
