A fiber laser is a laser that uses rare-earth-doped glass fiber as the gain medium. Fiber lasers can be developed based on fiber amplifiers: under the action of pump light, a high power density is easily formed in the fiber, causing a "population inversion" of the laser energy level of the laser working substance. When a positive feedback loop (forming a resonant cavity) is appropriately added, laser oscillation output can be formed.
Fiber laser marking machines use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, by causing physical changes in the surface material through light energy to "etch" a mark, or by burning away part of the material with light energy to reveal the desired etched patterns, text, barcodes, and other graphics.
Main features
1) Fiber laser marking machines are the most advanced laser marking equipment in the world today, featuring high beam quality, small size, high speed, long service life, flexible and convenient installation, and maintenance-free operation.
2) Fiber lasers consume little power, require no high voltage, and do not necessitate a large water-cooling system (only about 300W is needed).
3) The beam quality is high, close to an ideal beam, with its output center at 1064nm.
4) The overall lifespan is around 100,000 hours, which is longer than other types of laser marking machines.
5) The electro-optical conversion efficiency is over 28%, which is significantly higher than the 2%-10% conversion efficiency of other types of laser marking machines.
6) It has outstanding performance in energy conservation and environmental protection.
7) USB interface output control, optical scanning galvanometer, high laser repetition frequency, high speed and distortion-free.
Application Areas
It is widely applicable to graphic and text marking in many fields such as integrated circuit chips, computer accessories, industrial bearings, watches, electronic and communication products, aerospace components, various automotive parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military products, as well as mass production line operations.

Routine maintenance
1) When the fiber laser marking machine is not working, the power supply to the marking machine and the computer should be turned off.
2) When the machine is not in use, cover the field lens with the lens cap to prevent dust from contaminating the optical lenses.
3) The circuit is under high voltage when the machine is working. Do not attempt to repair it if you are not a professional, in order to avoid electric shock.
4) Power should be cut off immediately if any malfunction occurs in this machine.
5) Over time, dust from the air will accumulate on the lower surface of the focusing lens. This can reduce laser power and affect marking results, or even cause the optical lens to overheat and crack. When marking results are poor, carefully check the surface of the focusing lens for contamination.
6) If the surface of the focusing lens is contaminated, the focusing lens should be removed and its lower surface cleaned.
7) Be especially careful when removing the focusing lens to avoid damaging or dropping it; also, do not touch the lens surface with your hands or other objects.
8) The cleaning method is to mix anhydrous ethanol (analytical grade) and ether (analytical grade) in a ratio of 3:1, soak a long-fiber cotton swab or lens paper in the mixture, and gently wipe the lower surface of the focusing lens. The cotton swab or lens paper must be replaced after each side is wiped.
9) Do not move the marking machine while it is in operation to avoid damaging the machine.
10) Do not cover or place other items on the marking machine to avoid affecting the machine's heat dissipation.
