What is the marking principle of fiber laser machine?

1. The marking principle of the fiber laser machine is to irradiate the laser beam with high energy density under the control of the computer to the surface of the product to be marked, and ablate the desired graphics or text.

2. Fiber lasers have become a hot topic in laser physics research in recent years, and they are unanimously considered to be a new generation of products that have the potential to completely replace solid-state lasers. Fiber laser refers to the laser with rare earth element doped glass fiber as the gain medium, fiber laser can be developed on the basis of fiber amplifier: under the action of pump light, it is easy to form a high power density in the optical fiber, resulting in the laser energy level of the laser working substance "particle number reversal", when the positive feedback loop (forming a resonator) can be added appropriately to form a laser oscillation output.

Fiber laser marking machines use laser beams to mark permanent marks on the surface of various substances. The effect of marking is through the evaporation of the surface material to reveal the deep material, or through the physical change of the surface material caused by light energy"engraving"Traces, or through light energy to burn off part of the substance, to reveal the required etched patterns, text, barcodes and other graphics.

The principle of the fiber laser marking machine is the same as that of the laser marking machine, which is to irradiate the surface of the product to be marked with a laser beam with extremely high energy density under the control of the computer, and ablate the desired graphics or text. Compared with ordinary laser marking machines, the optical fiber is more advanced and the effect is better.

I don't know if my explanation will help you!

Fiber laser marking machine.

It is mainly composed of three parts: laser, galvanometer and marking card, and the marking machine that uses fiber laser to produce laser, the beam is the same, its output center is 1064nm, the life of the whole machine is about 100,000 hours, the life of the whole machine is about 100,000 hours, the life of other types of laser markers is longer, the electro-optical conversion efficiency is more than 28%, and the conversion efficiency of 2%-10% is very advantageous compared to other types of laser marking machines, and it has outstanding performance in energy conservation and environmental protection.

The same, except that the light passes through the optical fiber to travel down. It's just different from other direct transmissions.

The basic principle of laser marking is that a high-energy continuous laser beam is generated by the laser generator, and the focused laser acts on the substrate to make the surface material instantly melt and even vaporize, and by controlling the path of the laser on the surface of the material, the required ** mark is formed.

Laser marking is characterized by non-contact processing, which can be marked on any shaped surface without deformation and internal stress of the workpiece.

It is suitable for marking metal, plastic, glass, ceramic, wood, leather and other materials.

Lasers can be used on almost all parts (e.g. pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components).

etc.), and the marking is wear-resistant, the production process is easy to automate, and the deformation of the marked parts is small.

The ultra-fine laser beam after focusing is like a tool, which can remove the surface material of the object point by point, and its advancement lies in the fact that the marking process is non-contact processing, and does not produce mechanical extrusion or mechanical stress, so it will not damage the processed item; Due to the small size of the laser focus, the small heat-affected area, and the fine machining, it is possible to complete some processes that cannot be achieved by conventional methods.

Laser processing is used"Knives"It is the point of light that is focused.

There is no need to add additional equipment and materials, as long as the laser can work properly, it can be continuously processed for a long time. Laser processing is fast and inexpensive. The laser processing is automatically controlled by the computer, and there is no need for human intervention during production.

Laser marking is the use of a laser beam to make permanent marks on the surface of a variety of different substances. The effect of marking is through the evaporation of the surface material to reveal the deep material, or through the chemical and physical changes of the surface material caused by light energy"engraving"Traces, or through the use of light energy to burn off part of the substance, to reveal the desired etched pattern, text.

Laser marking machine is mainly divided into, CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine, laser marking machine is mainly used in some occasions that require finer and higher precision. It is used in electronic components, integrated circuits (IC), electrical appliances, mobile phone communications, hardware products, tool accessories, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes.
