What is a fiber laser and how is it used?

Table of Contents
A fiber laser is a type of laser in which the amplified light beam is created and transported through an optical fiber instead of through 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: Because they have no moving parts that can wear out, fiber lasers are very durable.
- Energy efficiency: They use less energy compared to traditional laser types.
- Low thermal impact: Fiber lasers have high efficiency, which means less heat generation and reduced risk of damage to sensitive materials.


How does a fiber laser work?
Fiber lasers uses an optical fiber, doped with rare earth metals such as erbium, ytterbium or neodymium, to generate and amplify laser light. The light is guided through the fiber, making it extremely focused and can be used to work with a variety of materials. The process occurs in three steps:
- Light generation: The light is generated by a diode laser and amplified in the doped optical fiber.
- Focusing: The strong light beam is directed through optical lenses to be focused to an extremely small point.
- Processing: The focused beam is used to engrave, mark, cut or weld materials.
Common uses for fiber lasers
- Engraving and marking
- Marking of metal objects such as tools, jewelry and industrial components.
- Permanent marking of plastic and electronics for traceability and branding.
- Welding
- Fiber lasers are used to weld metal components in precision industries such as aerospace and medical technology.
- Surface treatment
- Used to clean, polish or structure surfaces for improved adhesion or decorative effects.
