There are two distinct laser cleaning processes; coating removal and surface decontamination. The former is characterized by removing a layer of unwanted material from the surface of a substrate. It is most effective when the physical and chemical composition of the layer differs from the substrate. Such include insulation, primers, corrosion preventive coatings, rubber or paint. The latter involves removing the entire upper layer of the substrate and requires high flux laser beams.
The low-maintenance, easily automated process can be used to remove oil and grease, strip paint or coatings, or modify surface texture, for example adding roughness to increase adhesion. With the light handheld cleaning gun equipped, the cleaning process is more flexible and convenient. 3) Provide large-scale optical fiber equipment exhibition hall for customers to confirm the strength of our company. 3) Without any chemical cleaning fluid and no consume materials,safe and environment protecting.
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.
4.Without any chemical cleaning fluid and no consume materials,safeand environment protecting. Is established in July 2004 owns more than 500 square meters of researching and office space, more than square meters factory All machines, passed the European Union CE authentication American FDA cerificate and are certied to ISO 9001. South east Asia, Afica etc, more than 120 counties and areas, and supply OEM service for more than 30 manufactures. By adjusting other parameters, the laser beam is able to achieve the desired cleaning effect accurately and easily. The focused laser beam is capable of accurately evaporating surface objects or dirt.

In 2017, researchers at TU Munich demonstrated the smallest mode locking laser capable of emitting pairs of phase-locked picosecond laser pulses with a repetition frequency up to 200 GHz. Maiman’s functional laser used a flashlamp-pumped synthetic ruby crystal to produce red laser light at 694 nanometers wavelength. The device was only capable of pulsed operation, due to its three-level pumping design scheme.
These devices can generate high power outputs with good beam quality, wavelength-tunable narrow-linewidth radiation, or ultrashort laser pulses. Solid-state lasers or laser amplifiers where the light is guided due to the total internal reflection in a single mode optical fiber are instead called fiber lasers. Guiding of light allows extremely long gain regions providing good cooling conditions; fibers have high surface area to volume ratio which allows efficient cooling.
The laser cleaning machine adopts non-contact cleaning and does not damage the part matrix. Precise cleaning can realize selective cleaning with precise position and precise size. No chemical cleaning fluid, no consumables, safety and environmental protection. The operation is simple, and it can be powered on, and it can be hand-held or cooperated with a robot to realize automatic cleaning.
