Definition – What is A Fiber Laser Marking Machine?

Fiber Laser marking machine is now a hot type of CNC laser system which adopts fiber laser generator to leave permanent marks on different 2D/3D surfaces of metal and nonmetals. 

Our fiber laser marking systems are mainly divided into Portable series, Desktop series, Flying series, 3D series, etc. Fiber laser markers are widely used in hobbyists, small businesses, small shop, home shop, home business, school education, industrial manufacturing, and commercial applications.

Fiber Laser marking machines are also known as fiber laser markers, fiber laser marking systems, fiber laser engraving machines, fiber laser etching machines, fiber laser stippling machines, fiber laser labeling machines, fiber laser printing machines and fiber laser marking equipment.

Working Principle – How Does a Fiber Laser Marker Work?

Fiber laser marking machine uses a laser beam with extremely high energy density, through computer control, to make permanent marks on the surface of various materials. The effect of marking is to reveal the deep material through the evaporation of the surface material, or to “engrave” traces of the surface material through physical changes caused by light energy, or to burn off part of the material through light energy to reveal the desired etched patterns, text, bar codes and other kinds of graphics.

Fiber laser marker is a laser using rare earth element doped glass fiber as the gain medium. Fiber lasers can be developed on the basis of fiber amplifiers: high power density is easily formed in the fiber under the action of pump light, causing the laser energy level of the laser working material to “particle number reversal”, when properly added to the positive feedback loop (forming a resonant cavity) can form the laser oscillation output.

Applications – What Are Fiber Laser Markers Used for?

Fiber laser marking machine is widely used in integrated circuit chips, computer parts, industrial bearings, clocks and watches, electronic and communication products, aerospace devices, various automotive parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military affairs and many other fields of graphics and text marking, as well as mass production line operations.

What Are the Advantages and Benefits of Fiber Laser Marking Equipment?

1.It can process a variety of metal and non-metal materials. Especially for high hardness, high melting point, brittle materials, marking is more advantageous.

2.It is non-contact processing, no damage to the product, no tool wear, good marking quality.

3.The laser beam is fine, processing material consumption is very small, processing heat-affected zone is small.

4.High processing efficiency, computer control, easy to achieve automation.

5. The life of the whole fiber laser marking machine is about 100,000 hours, which is longer than other types of laser markers.

6.The electro-optical conversion efficiency is more than 28%, which has a great advantage compared to 2%-10% conversion efficiency of other types of laser engraving machine. It has outstanding performance in energy saving and environmental protection and other aspects.

How Does a Fiber Laser Marking Machine Work?

Main Parts

A fiber laser marker is an automatic laser marking machine composed of fiber laser generator, laser power supply, galvanometer scanning system, field lens scanning system, beam combiner, computer control system, focusing system, laser software, machine frame, red light indicator, laser marking control card, power filter, and more laser parts & accessories.

Ho to Work

The laser generator provides a laser source, which is expanded by the fiber and imported to the XY mirror of the scanning galvanometer. The combined control of marking software, scanning galvanometer and laser generator can mark permanent text or patterns on the workpiece.

Fiber laser generators have become a hot topic in laser physics research in recent years. It is unanimously considered as a new generation product that may completely replace solid-state laser generators. Fiber laser generator refers to a laser generator that uses rare-earth-doped glass fiber as the gain medium. The laser generator can be developed on the basis of a fiber amplifier. Under the action of the pump light, high power density is easily formed in the fiber, causing the laser energy level of the laser working substance to “populate number inversion”. When a positive feedback loop (forming a resonant cavity) is properly added, the laser oscillation output can be formed.

The laser generator is composed of a working medium and a pump source enclosed in a pump cavity. The pump source “pumps” the working medium from the energy ground state to the excited state. If the “population inversion” is achieved between the two excitation energy levels, stimulated radiation (ie photons) can be generated, which can be amplified by resonating in the optical cavity and reflecting back and forth. A part of the amplified electromagnetic radiation is output to form a laser. The laser generator introduces the 1064nm high-power laser directly into the processing surface through a soft single-mode fiber with a sheath, and the spot size after collimation and focusing reaches tens of microns or less, which is close to the diffraction limit. This type of laser can be used for marking, etching, burning, printing, or engraving various materials.
