The unique properties of the laser beam have long been used in medicine, in the manufacture of high-precision devices, in laboratory facilities, etc. A narrow beam of coherent electromagnetic radiation in the optical range has long attracted researchers from all over the planet. The properties of the laser are well studied and have recently been used in the national economy and in production. Probably, everyone saw high-precision sights or well-known pointers in the work. The power of such devices is small, but it is quite enough to demonstrate them
opportunities. With the development of manufacturing technology, small-sized elements capable of delivering a beam of sufficiently high power are now being industrially produced. No doubt they will find their place in electronics. Based on them, it is quite possible to make a home-made laser that can be used in everyday life, for example, as a small-sized level gauge.
In order to make a homemade laser, there is no need to look for an expensive crystal, design a pumping device, install a reflector, etc. To youyou don't even need to adjust the special optical lens used to correct the beam. At the moment, the technology for manufacturing laser diodes is quite well developed.
Such a device can operate with a constant radiation power of up to 8 watts, which is quite enough to get a long beam. At close range, such a device will burn through a sheet of paper. All that is needed in order to assemble such a homemade laser is to pick up a case and organize a power source. It should also be borne in mind that when turned on, such a device consumes a decent current, and ordinary batteries will soon have to be changed. Batteries are the best source of power. Depending on the purpose of such a device, you can refer to the catalogs and select a diode according to the parameters of the consumed current and radiation power that suit you best.
Laser diodes are widely used in a wide variety of electronic devices. It is quite possible to dismantle this device from an old laser "cutter" for DVD discs and make a homemade laser out of it. It is quite suitable for demonstrating the capabilities of this device.
Currently produced laser lines with a peak output optical power of up to 150 watts. Keep safety in mind when working with these items.
If you are going to assemble a powerful device capable of processing fusible materials, then youplasma cutting is useful. With your own hands, this device can be assembled on the basis of drawings, which can be found in the public domain.
As you can see, it is quite possible to make homemade lasers without resorting to searching for expensive and scarce materials. Assembly and calibration will not take much time.
The range of produced laser diodes is constantly growing. Their output optical power is increased. In-line production leads to a gradual decrease in their cost.
