What is the best laser source for a laser cleaning machine?

Laser cleaner, as the name suggests, is a kind of equipment that utilizes laser technology for cleaning. Its working principle is to irradiate the surface of the object to be cleaned by a high-energy laser beam, so that the surface dirt, oxidized layer or other impurities are instantly evaporated, decomposed or stripped, thus achieving the effect of cleaning. Laser cleaner has the advantages of non-contact, non-pollution, high efficiency, controllable, etc. It is widely used in the field of cleaning and processing of various materials such as metal, non-metal, composite materials and so on.

4 laser sources of laser welding machine

The common laser sources on the market mainly include fiber laser, MOPA laser, CO2 laser, UV laser and so on. They each have their own characteristics and scope of application.

Fiber laser has the advantages of stable output power, high conversion efficiency, strong anti-interference ability, long life and so on, suitable for large-scale, high-efficiency cleaning operations. For some large-scale steel structures, pipelines, etc., due to the large size of the heat dissipation is fast, then you can choose the fiber laser.

MOPA laser meets various material surface cleaning. Laser cleaning is one of the most widely used, with adjustable output power, good beam quality, no need for optical lenses and other advantages, suitable for scenes requiring high cleaning accuracy, especially widely used in new energy batteries and other emerging industries.

Carbon dioxide laser is a gas laser with CO2 gas as the working material, which is filled with CO2 gas and other auxiliary gases (helium and nitrogen as well as a small amount of hydrogen or xenon), with better directionality, monochromaticity and frequency stability. It is a good choice for cleaning the surface of non-metallic materials such as adhesive removal, coating removal, and ink removal.

UV laser with short wavelength and high single photon energy can directly interrupt the chemical bond between materials, and the materials are stripped off the surface in the form of a gaseous state or particles. UV lasers, on the other hand, because of their short wavelength and high energy, the cleaning effect on certain polymer materials is particularly significant. It is the best laser cleaning program in the field of precision electronics.

3 tips of choosing laser cleaning machine

When choosing a laser cleaner, you need to decide the most suitable laser source according to the cleaning object and demand. For example, for the cleaning of metal materials, fiber lasers, and MOPA lasers are good choices; for non-metallic materials, especially polymer material cleaning, CO2 lasers, and ultraviolet lasers are more able to play their advantages.

So, how to choose the right laser source and laser cleaning machine?
First of all, to clarify the cleaning object and cleaning effect requirements, such as cleaning accuracy, speed, material type, etc..
Secondly, to understand the characteristics and scope of application of various laser sources, from which to select the laser source that meets the needs.
Finally, but also consider the brand, performance, price and other factors of the laser cleaning machine, comprehensive assessment to make a choice.


Overall, with its unique advantages, the laser cleaning machine is gradually replacing the traditional cleaning method and becoming the new favorite in the modern cleaning field. No matter which industry you are engaged in, no matter what kind of material you need to clean, you can find a suitable solution from the laser cleaning machine. I believe that with the continuous development of laser technology, the application of laser cleaning machines will be more broad prospects.
