Very often, in the wording of various online publications technical orientation receive letters with requests to show and tell how to make the laser itself at home.Typically, such requests are due to the limited financial capacity of the users.
laser - a device that emits a concentrated light beam of a certain spectrum.This light can be amplified stimulating radiation.Everyone knows that the laser has unique features of its kind, which are used for cutting, welding and soldering of parts from a variety of materials.These unique properties are often used in medicine and cosmetology (bloodless scalpel and laser epilators).Often, this kind of devices in daily life can be found in all kinds of players, printers, barcode readers, and, of course, the laser pointer.That they will be used here to tell you how to make a powerful laser.
In order to make the laser in makeshift conditions, we need the following materials:
-
flashlight;
-
laser pointer (it is necessary in the event that will be made laser cutter);
-
batteries (best to take powerful batteries);
-
DVD-RW drive.
As a rule, the drive is taken b / y, or broken.It is very important - for the laser needs a "cutting" the drive, ie,a drive which at the time could burn discs.This is one of the main characteristics that should be taken into account to create a powerful laser.In order to let you know of any drive, a laser power can be extracted, we present the following list:
-
drive speed - 16x, the laser power - 200 mW;
-
drive speed - 20x, the laser power - 270mVt;
-
drive speed - 22x, the laser power - 300mW.
So we are told that it is necessary to build a laser.Now tell what should be done to fully understand how to make a laser.Read the following instructions.
Step One
If you want to learn how to make a laser pointer, you need to follow these instructions.
The first thing we need to do - is to disassemble the DVD-ROM drive and pull out all the unnecessary details.The most important detail, which we have to do very carefully - this LED laser.Typically, in any DVD-drive has a similar laser.The only difference between them may be - is the difference in power.Table of them you can find at the beginning of this article.Be careful, there are recorded two lasers: one that we need, and the infrared laser.To distinguish from each other can be requested by the presence of a large heatsink.Important and necessary for us, the laser is more sensitive to static electricity.In order to reduce the risk of damage to it, you can wrap the wires contacts thin-plugs.In this state, he will lie as long as we do not start to collect the laser.
Step Two
next stage of action, how to make a laser, is the extraction of the LED laser pointer and prepare the body of our device.In order to get a diode, we can use a pair of tweezers.
Step Three
Everything is ready for the assembly of our laser.First, let's check the polarity of our laser eye, which we got from the DVD-drive.Typically, the diode polarity "languages" is spread on the same principle.If you are in doubt, you can check it out with conventional rechargeable batteries.It should be noted that the laser diode is in any case can not be connected directly to the battery.Use limiting resistor 3-5Om intervals.This categorization stems from the fact that the details of the sample are not linear circuits and components are not compatible with direct voltage.After checking we connect our laser and the anode to the cathode in the bidding.
Step Four
Parse flashlight.We take out the bulb and reflector ring.The reflector ream the hole for the radiator with the expectation that he "became" as closely as possible.Then collect a flashlight in reverse order.Usually, people get it right, and the question: "How to make a laser?" Disappears automatically.
