The operation of fiber lasers

A fiber laser is a powerful device for the production of single-mode radiation with the highest possible performance and quality characteristics. Fiber optic systems for processing materials occupy about one-fourth of the entire laser market. 

It should be noted that the diameter of the fiber laser system has micro values, so the laser beam allows for cutting out sharp corners and other complex shapes with absolute accuracy, even in a sheet of metal with high hardness and large thickness.

The beam formed by a fiber laser is designed primarily for working with metal surfaces, so the fields of application include automobile, ship and rocket engineering, manufacturing of sea containers and railway cars, machine tool construction, robotics, marking and engraving, and the military-industrial complex.

In addition to metals, the fiber laser is perfect in working with stone, glass, and some types of plastic, so it is also used in those industries that massively use these materials (for example, the advertising industry, some types of construction work, etc.).

The priority in using solid-state equipment (fiber lasers belong to this category) over any other systems is explained by a large number of economic and qualitative advantages, which are the following:

  • positioning accuracy at all speed modes;
  • high power;
  • excellent laser beam quality with minimal transmission loss and small angular divergence;
  • multi-function: laser systems can not only cut, engrave and perforate materials, but also solder or perform welding, and cleaning of surfaces from any type of contamination;
  • compact size, easy transportation;
  • silent operation and almost complete absence of industrial waste.

The fiber laser system consists of two main parts: pump lamps (semiconductor diodes) and fiber optic cable. A light-conducting optical fiber with a core of transparent quartz doped with rare earth elements is inside the cable (this is ytterbium in most machines used in industry). 

At the ends of the central rod, a fiber Bragg grating (FBG) is most often performed. The notched sections have a modified reflectivity and act as resonators, reflecting light propagating along the optical fiber and maintaining the desired wavelength. The laser beam retains its monochrome and other quality characteristics thanks to them.

Optromix is a manufacturer of laser systems, optical fiber sensors, and optical monitoring systems. We develop and manufacture a broad variety of fiber lasers, high-powered fiber lasers, and other types. We offer simple laser products, as well as sophisticated fiber laser systems with unique characteristics, based on the client’s inquiry. 

We manufacture laser modules using our technologies based on the advanced research work and patents of the international R&D team. Laser processes are of high quality, high precision, easily-automated manufacturing solutions that provide repeatability and flexibility.
