Fiber Laser Marking Machine is widely used for marking on various materials like metals, plastics, and ceramics. They are known for their high precision and accuracy in marking. The process of marking is done by using a high-intensity laser beam. This article explains the working principle of fiber laser marking machines.
Fiber Laser Technology The fiber laser technology used in fiber laser marking machines is based on the theory of stimulated emission. Laser energy is generated through a laser diode inside the fiber optic cable, which is surrounded by the fiber cladding. The fiber optic laser creates a high-quality laser beam that is used for marking on various surfaces. Marking Process In the Fiber Laser marking machine, the marking process is carried out by the laser beam, which penetrates the material and causes a change in its color. The laser heats the material to a temperature that causes oxidation or physical deformation of the material, resulting in a visible mark. The process of marking is carried out in a short time, ranging from nanoseconds to microseconds, depending on the power and pulse width of the laser beam. Types of Marking The fiber laser marking machine can mark on the surface of the material (surface marking) or inside the material (deep marking). Surface marking is suitable for metals, plastics, and other materials, while deep marking can be done on metals and some other materials. Laser Beam Control The laser beam in fiber laser marking machines is controlled by using scanning mirrors and lenses. The mirrors and lenses direct the laser beam onto the surface of the material and focus the beam to a small spot size. The spot size determines the precision of the mark that is made on the surface of the material. The laser beam can be controlled to form characters, logos, barcodes, and other patterns. Applications Fiber laser marking machines are widely used in various industries like automobile, aerospace, electronics, medical, and jewelry. They are used for marking products with information like serial numbers, bar codes, lot numbers, and logos. Fiber laser marking machines are also used for engraving on the surface of promotional products like pens, keychains, and USB drives. In conclusion, fiber laser marking machines are known for their high precision and accuracy in marking. The process of marking involves using a high-intensity laser beam that heats and changes the material's color to form a visible mark. Fiber laser marking machines are widely used in various industries and are suitable for marking various materials.
