A fast, reliable and precise solution for harder materials. The fiber laser is a red light laser that generates heat, i.e. emits heat. Excitation is carried out with light emitted by diodes. The construction of fiber lasers does not require beam chambers, sensitive mirrors and lens systems, as the beam is guided to the material to be processed on an optical fiber.
The energy density of a beam created by a 2.5 kW fiber laser at the focal point can be up to five times that of a 4 kW CO2 laser. The wavelength of the laser beam created by fiber lasers is 1 micrometer, this is the parameter that significantly affects the absorption of the laser beam, i.e. the ability of the material to be processed to absorb the energy of the laser beam. Which laser can be used to perform the desired task more effectively depends on the material of the workpiece, since a material has different absorption and reflection properties in different wavelength ranges. Due to its strength, it is recommended to be used mostly on harder materials, including metal surfaces, e.g. aluminum, copper, chrome, titanium, iron, steel.
A low-heat, high-performance solution for more fragile materials.
With the uv laser, it is important to emphasize that it performs the task with low heat, so the processing involves minimal heat release, so material torsion does not occur. We get a cleaner final product because this type of laser is used for softer, more fragile materials. For example, when marking a plastic, it does not burn or melt the material, so we get a perfect and appreciable result.
In case of marking, even the contrasts between the materials are clearly visible and the UV laser equipment provides better readability. Burrs are not created during the processes and discoloration will not occur, so it does not require post-work.
It can be easily applied to plastic, glass, Plexiglas and other more fragile materials, including PCB, silicone, ceramic and paper.
High-performance solution with good beam quality.
The CO2 laser is a continuous gas laser, the resonator is located in the laser machine, in which the medium is typically nitrogen, helium, hydrogen and carbon dioxide. Excited with a high-voltage current, laser light is generated with the help of the nitrogen present.
The resulting beam exits the medium through a semi-transparent mirror. Special mirrors and lenses guide the light to the area to be worked on. During the formation of laser light, heat is generated, so the resonator and the medium must be continuously cooled. The laser light produced by the CO2 laser has a wavelength of about 10 micrometers.
Because of the materials in it, it is more difficult to use than a fiber or a UV laser and its size is also completely different, so its flexibility is not as outstanding as that of the two aforementioned lasers. It can be used on wood, metal, glass, granite, Plexiglas and even textiles.
