Laser marking and laser engraving are two exceptionally advanced, but yet based on a simple scientific principle technological inventions. These methods are used in a variety of industries like the automotive industry, electronic parts manufacturing, medical & scientific parts manufacturers and so on. In the recent aerospace research sector laser marking has been the most preferred method to make markings on vital and critical components of the equipment and space vehicles as well. While discussing about laser marking machine, the most common methods of execution are annealing, carbon migration, engraving, etching and coloration. In order to understand how this technology works on different material surfaces, it is very much necessary to know the principle on which it is based.
To put it in a very simple sense, it works by focusing a beam of light amplified by the stimulation and emission of radiation, which is focused and fixed towards a particular area on the material surface. Since a laser beam is enthused to discharge elements of light, this beam carries a certain amount of energy that is released which is assessed in wavelengths .The greater the wavelength, the more potent the laser beam will be.
When the beam thus released comes in contact with the material surface, it apparently modifies the material surface properties and to some extent its appearance as well. The main advantage in this laser beam is that it targets only a specific area, enabling the laser beam to create a precise and high quality marks virtually on all surfaces, barring some materials which are delicate and sensitive to high temperature. Due to this wide range of applications on a variety of material surfaces, laser marking is considered as an ideal technology where the aspects of precision and durability are needed.
Although the science involved in the technology of lasers and laser marking machines, is quite straight and simple, because of the fact that at their concentrated point, a considerable amount of heat that is generated, that is at the point of contact it may not be the preferred method for certain softer and heat sensitive material surfaces, in such cases, a reformed type of laser machine the UV laser or cold laser beam that practically emits less energy and heat they are a the most preferred solutions for marking many soft products and heat sensitive materials.
