Several types of laser marking machines exist, but the most up-to-date technology available is that of the fiber laser. This kind of laser machine, widely considered to be the best option in existence, uses fiber pumping technology to “dope” the fibers with a rare-earth element such as Ytterbium.
The use of this element increases the ability of the fibers to conduct light-emitting diodes, which are then pumped through the fibers to the optical heads. At that point, the beam of light expands to create the laser marking capability.
One of the benefits of using fiber markers is minimal part replacement - the diodes have a significant lifespan so there’s no need to budget extensively for parts. When they need replacement, it can be done in the field without requiring a qualified technician to perform any laser alignment.

You can use fiber laser marking on a wide range of materials, from different types of metal through to leather and plastics. Types of metals that lend themselves well to fiber laser engraving include platinum, stainless steel, silver, gold and bronze. Carbide, tungsten, copper, aluminum or medical-grade alloys also respond well to fiber laser marking.
Medical Devices and Equipment – surgical devices and other medical products that require frequent sterilization (often at high temperatures) use identification marks that can withstand the cleansing process without interfering with the health of the patient.
Jewelry Engraving – creation of unique marks to identify or brand items of jewelry has become popular for copyright protection and recovery of stolen property. The precision of laser engraving is also used to personalize pieces such as wedding bands with the vows or the couple’s marriage date.
Laser Cutting - light laser cutting is also very popular in the jewelry industry. Light metals are used to create name cutouts and monograms as well as other design cut outs.
Computerized parts such as printed circuit boards use laser marking to produce clear, high-resolution images that are ink- and acid-free for use in electronic applications.
