Many lasers produce a beam that can be approximated as a Gaussian beam; such beams have the minimum divergence possible for a given beam diameter. Some lasers, particularly high-power ones, produce multimode beams, with the transverse modes often approximated using Hermite–Gaussian or Laguerre-Gaussian functions. Some high power lasers use a flat-topped profile known as a “tophat beam”. Specialized optical systems can produce more complex beam geometries, such as Bessel beams and optical vortexes. The gain medium is put into an excited state by an external source of energy.

In 1928, Rudolf W. Ladenburg confirmed the existence of the phenomena of stimulated emission and negative absorption. In 1939, Valentin A. Fabrikant predicted the use of stimulated emission to amplify “short” waves. Retherford found apparent stimulated emission in hydrogen spectra and effected the first demonstration of stimulated emission. In 1950, Alfred Kastler proposed the method of optical pumping, experimentally confirmed, two years later, by Brossel, Kastler, and Winter. The mechanism of producing radiation in a laser relies on stimulated emission, where energy is extracted from a transition in an atom or molecule. This is a quantum phenomenon discovered by Albert Einstein who derived the relationship between the A coefficient describing spontaneous emission and the B coefficient which applies to absorption and stimulated emission.

For emerging laser cleaning applications, there are questions about whether the CW fiber laser or pulsed fiber laser should be used. Here, we compare the laser cleaning applications of CW fiber lasers and pulsed fiber lasers, and analyze their respective characteristics and applicable application scenarios. This article provides useful reference when choosing the corresponding laser cleaning technology. Fiber Laser Cleaning Machine can be used for a variety of industrial cleaning with laser applications, such as paint removal, preparation treatment, oil and oxides (e.g. rust) removal, mould cleaning, tool cleaning in addition to labelling and marking. It can meet the requirements of equipment cleaning in the ship building industry, auto parts, rubber molds, high-end machine tools, tire molds, rails, environmental protection industry and other fields.

Laser cleaning uses a machine that aims a laser pulse at high power onto the rusty surface of a material. The laser energy is absorbed by the organic material lying on the surface of the substrate while the non-organic substrate remains untouched. Laser cleaning, also known as laser ablation, uses a laser beam to remove impurities and contaminants from the surface of a material through irradiation.

It is widely used in metal material cleaning as well as coated cleaning on surfaces such as stainless steel, carbon steel and coated products. With a laser cleaning machine, you can ablate any rusted surface in your home. This handheld laser cleaning machine can quickly remove dust, coating, painting, oil and other contaminants on the surface of the work pieces. Users can hold the cleaning gun and clean any specific positions as needed.

Laser cleaning removes coatings, contaminants, rust, and residues with a non-contact, non-abrasive high-energy laser beam which leaves the substrate untouched. CleanTech is the most cost-effective, efficient, and safest method of industrial cleaning, rust removal, paint removal, and surface preparation. Utilizing our proprietary technology, CleanTech cleans materials faster and better than other systems on the market. Our company manufactures lasers for engraving, marking, cutting and related applications. Our engravers are universally mountable, can be controlled by the PWM spindle signal and powered by 12 – 24 V, allowing them to be quickly connected to a wide range of CNC machines. These laser heads can also be mounted inside most 3D printers due to their design that is both lightweight and compact.

These materials are pumped optically using a shorter wavelength than the lasing wavelength, often from a flashtube or from another laser. The usage of the term “solid-state” in laser physics is narrower than in typical use. Semiconductor lasers are typically not referred to as solid-state lasers. In 2017, researchers at TU Delft demonstrated an AC Josephson junction microwave laser. Since the laser operates in the superconducting regime, it is more stable than other semiconductor-based lasers.

The Opt Lasers brand manufactures the fiber laser modules that generate a red, green, or blue laser beam. Also, in our offer, you will find a wide range of accessories for CNC lasers, among others the laser optics, e.g., laser diode collimators, fiber optic lenses, HR mirrors, rotators. Our CNC laser and accessories can be used for a variety of CNC routers and home CNC machines, for example, X-carve, Stepcraft, Shapeoko, Openbuilds, and many more. Moreover, our small engraving laser heads are perfect for 3D printers. Your 3D printer with the blue laser head becomes the 3D printer laser engraver. We design and manufacture CNC lasers for industrial applications as well as the laser systems for research applications.

You are at liberty to adjust this width to your preference, depending on the surface material in question. Scrubbing rusted surfaces significantly degrades the substrate due to friction. Rust removing chemicals, on the other hand, are harsh and corrosive, causing wear and tear that could spoil delicate metals or even weaken their robustness. Laser cleaning in comparison ablates the surface while leaving the substrate untouched.

The door where the laser cleaning machine space is placed needs to have interlock control and a warning sign is attached to limit the operation. Fiber laser technology is a great alternative to chemical cleaning, sandblasting and the like. You get to remove surface contaminants with laser light alone, without using consumables. They emit laser light that removes rust and other contaminants quickly without damaging the metal substrate. Optimized for short cycle times, the rotary cleaning machine uses just a few seconds of the robot’s time to load parts onto one side of the rotary table while laser cleaning occurs in hidden time on the other side. With a high-quality laser source at their heart, you can expect to continuously operate them with minimal maintenance for at least 10 years.
