Laser Engraving, Marking And Etching: An Overview Of Associated Aspects
The word Laser is an abbreviation which marks the process that is carried out by using a highly focused beam of light that is created by the stimulated emission, which is amplified to the desired extent where in the beam thus generated will leave a mark on the surface of a material. When this highly focussed beam gets in contact with the material’s surface, it changes the material’s physical property and appearance. While this focussed beam aims at a specific area, a precise, contrasted mark is formed. Laser marking process makes it ideal for material surfaces which require accuracy and permanency. With the advancement of science and technology, the recent technically progressive cutting-edge fiber laser technology has been on the trend, belonging to the solid-state lasers category, they have a shorter wavelength due to which a smaller focal diameter beam is created or formed the point of impact on the material surface. In this case the intensity is many folds greater t
