What is a fiber laser and how is it used?

A fiber laser is a type of laser where the reinforced light beam is created and transported through an optical fiber instead of by mirrors or crystals as in other laser types. It is known for its high efficiency, precision and versatility and is used in many industries.

Properties of fiber lasers

• High precision : Can create detailed patterns with minimal material waste.
• Speed : Fiber lasers are faster than many other types of lasers, making them ideal for mass production.
• Long service life : Since they do not have moving parts that can be worn out, fiber lasers are very durable.
• Energy efficiency : They use less energy compared to traditional laser types.
• Low heat influence : Fiber lasers have a high efficiency, which means less heat development and reduced risk of damage to sensitive materials.

How does a fiber laser work?

Fiber lasers use an optical fiber, doped with rare soil metals such as Erbium, Ytterbium or Neodymium, to generate and enhance laser light. The light is led through the fiber, which makes it extremely focused and can be used to work with a variety of materials. The process takes place in three steps:

1. Light generation : The light is generated by a diode laser and is reinforced in the doped optical fiber.
2. Focusing : The strong beam of light is led through optical lenses to focus to an extremely small point.
3. Processing : The focused beam is used to engrave, label, cut or weld materials.

Common uses for fiber lasers

1. Engraving and marking
   • Labeling of metal objects such as tools, jewelry and industrial components.
   • Permanent labeling of plastic and electronics for traceability and branding.
2. Welding
   • Fiber lasers are used to weld metal components in precision industries such as aviation and medical technology.
3. Surface processing
   • Used to clean, polish or structure surfaces for improved adhesion or decorative effects.

Benefits of fiber lasers

• Can be used on a variety of materials, including:
  • Metals : stainless steel, aluminum, copper and titanium.
  • Plastics : Polycarbonate, ABS and other technical plastics.
  • Ceramics and composites : for specialized applications.
• Requires minimal maintenance and has low operating costs.
• Compatible with advanced CNC machines and automation systems.

Fiber lasers are used in many different industries:

• Manufacturing industry : For labeling machine parts and tools.
• Pharmaceutical and medical technology : engraving traceability codes on medical instruments.
• The electronics industry : Labeling of small components such as circuit boards and contacts.
• Jewelry industry : For engraving and polishing jewelry with high precision.
