A Review: Effect of Different Laser Types on Material Engraving Process
The laser is a non-traditional device used in many applications because it is a versatile flexibility and cost-effective. In this paper, different laser types of engraving different material were discussed for different fundamental researchers on laser engraving. Laser engraving is very practical to engrave hard and various material by removing part of layer from the surface to a specific depth. The effect of laser parameters such as wavelength, pulse duration, repetition-rate and mode of operation has studied various types of material. Also, the effect of material properties such as optical and physical properties with respect to incident laser radiation was studied. There are many kinds of industrial laser which are used for engraving like, carbon dioxide (CO2) laser, Neodymium-doped Yttrium Aluminum Garnet (Nd: YAG) laser, fiber laser and others. This review discussed the effect of three types of laser engraving on different material. With a sample comparison explains a summary of each author and the type of laser, material with the result and their application speed.
