In addition to its unique features such as monochromaticity, coherency, high intensity and low divergence; the laser beam has other special characteristics that result in its industrial practical developments, qualitative modification of the manufactured products and the increase in the products. In this article, we will express some of these features including very high accuracy along with a very small light spot and no product deformation during the cutting process. Due to the very short durations of the laser pulses, these features make possible their vast applications in the industry

With a glance to the laser role in the industry, we realize that the laser creates huge developing changes in this field. Today, laser-made artifacts with excellent quality are designed, manufactured and marketed in the shortest possible time. So, the impact and importance of the laser in industry is undeniable.

In addition to its unique characteristics such as monochromaticity, coherency, high intensity and low divergence; the laser beam has other special characteristics that result in its industrial practical developments, qualitative modification of the manufactured products and the increase in the products. Some of these features are mentioned bellow:

1.     Very high accuracy of lasers

 

Since the CNC and scanner parts of the laser devices are digitized and don’t have the time delay of the drill movements in the old methods, one can say that the laser devices are more than 10 times accurate than the traditional and manual methods.

 

2.     High working speed

 

Engraving speed in scanner devices depends on the scanner model and varies from 2000 mm to 5000 mm. This high speed of engraving lasers allows the engraving operation to be completed in a few seconds. Also, more than 300 letters per seconds can be engraved.

 

3.     Engraving and cutting spot on the order of 30 micron to 100 micron

 

The spot of the engraving and cutting laser is between 30 to 100 micron. This is resulted in laser engraving and cutting with a very high accuracy (more than ten times accurate compared to the old methods of cutting with blade). Hence, it is possible to print very small signs and logos of any shape with micrometer accuracy on wood, glass and even metals. While the thinnest pens that engrave with drills and the thinnest cutting blades are at least a few millimeters wide (more than 10 times larger than the laser spot).

 

4.     Engraving and cutting operations are performed before melting and deforming the material, to reduce the deficit of laser engraving and cutting work on the gold

 

The pulse duration of engraving and cutting lasers is about 10 to 100 nanoseconds (one million times smaller than 0.1 seconds). This very short pulse duration prevents the material from deformation during the laser cutting process (the time required for the materials to deform due to heating is about 1 millisecond). In other words, in laser cutting, the beam, which is focused on the working piece by a lens, generates a temperature of more than 4000 ° C on the working piece (metal) in less than one millionth of a second. This high laser speed greatly reduces the work deficit in gold engraving and cutting.

 

5.     The simplicity of working with the system and user-friendly capabilities

 

Since all the control and guidance parts of these laser engraving and cutting systems are done by a computer, users will be able to do it with the least skill.

 

6.     Laser engraving has no serious restrictions on the type of material and can pierce the hardest metals such as diamonds or perform the most delicate surgeries such as eye surgery

 

The laser beam is much brighter and intensive than any natural light. It is possible to generate a very powerful laser light capable of vaporizing any known material on the earth in a fraction of a second. In contrast, the low-power and ultra-precise beam of other types of lasers can be used to perform very delicate tasks, such as surgery on the human eye. Laser light can be very precisely controlled and converted into a continuous beam called a continuous wave or it can be converted into a fast burst called a pulse.

 

7.     Make micrometer holes in various materials such as glass and plastic

 

Micrometer drilling is almost impossible without the use of lasers. Nowadays, with the help of lasers, this operation can be performed and repeated at a high rate and in less than a second. This is what craftsmen have been looking for many years.

 

8.     Due to their high flexibility, fiber lasers allow engraving, cutting and welding in places where older machines cannot enter

 

9.     The ability to perform very fine micrometer welds

 

In industry, lasers are also used for heat treatment of metals, welding of parts to each other and in precise alignment devices.

 

10.                         Lasers are used to accurately measure very large distances of several hundred kilometers as well as very small distances of several micrometers

 

By using a laser, distances of more than 100 km can be measured with an accuracy of a few centimeters in less than one millisecond. Conversely, holographic lasers in the industry can detect and show a difference of less than one thousandth of a millimeter of a 30 cm material in less than one thousandth of a second.
