It is environmentally friendly, which causes the surface dirt, rust or coating to evaporate or peel off, and effectively removes the surface adhering or surface coating of the cleaning object at high speed. It is easy to remove resin stains, paint-coat, rust, cladding material, and paint. It is widely applicable in varies of industries, which can effectively reduce the machine maintenance cost and improve the industrial cleaning effect. Intuitively, the materials are darker after cleaning by a CW fiber laser when compared with a MOPA pulsed fiber laser .
These modes are a property of the single-mode fiber used, rather than a thermal operating point. Consequently, fiber lasers, unlike other solid-state lasers, produce the same beam profile, with no change in divergence over their entire operating power range, typically from 10% to 100% of specified power. The overall pumping method is more than 50% electrically efficient and produces single-mode output of around 2 to 3 kW of continuous-wave power from a single module.
For light, this means that any given transition will only absorb one particular wavelength of light. Photons with the correct wavelength can cause an electron to jump from the lower to the higher energy level. A laser that produces light by itself is technically an optical oscillator rather than an optical amplifier as suggested by the acronym.
Unfortunately, such methods only offer a temporary solution to rusting. Electrolysis is a better approach to the problem, but that will require a car battery charger, baking soda, a basin of water, and a sacrificial metal composed of iron. I bet you are already rolling your eyes at the list of components needed for this. Fortunately, there’s a simpler, and more thorough approach to rust removal; laser cleaning.
Theodore Maiman characterized the first laser as having a power of one “Gillette” as it could burn through one Gillette razor blade. Today, it is accepted that even low-power lasers with only a few milliwatts of output power can be hazardous to human eyesight when the beam hits the eye directly or after reflection from a shiny surface. When lasers were invented in 1960, they were called “a solution looking for a problem”.

In 2012, Nichia and OSRAM developed and manufactured commercial high-power green laser diodes (515/520 nm), which compete with traditional diode-pumped solid-state lasers. Recombination of electrons and holes created by the applied current introduces optical gain. Reflection from the ends of the crystal form an optical resonator, although the resonator can be external to the semiconductor in some designs. In 2015, researchers made a white laser, whose light is modulated by a synthetic nanosheet made out of zinc, cadmium, sulfur, and selenium that can emit red, green, and blue light in varying proportions, with each wavelength spanning 191 nm. External audio “The Man, the Myth, the Laser”, Distillations Podcast, Science History InstituteThat same year, Charles Hard Townes and Arthur Leonard Schawlow, then at Bell Labs, began a serious study of infrared “optical masers”. As ideas developed, they abandoned infrared radiation to instead concentrate on visible light.
Numerous feedback from our clients has proven that our laser rust removal machines are stable in performance with rare malfunction. The overall electro-optical efficiency of commercial fiber lasers is as high as 25%, which is conducive to cost reduction, energy-saving, and environmental protection. Special custom laser and galvo scanner head, high cleaning speed, to meet various high-level laser cleaning application demands. Professional laser cleaning optical design, high damage threshold of scanning mirrors, high beam transmittance and large focus depth of F-theta lens, can meet long-time working of high-power laser cleaning. Another advantage brought by the MOPA fiber laser is high cleaning efficiency.
1)Powerful, short pulses, fast moving laser pulses act on the surface of the target, producing tiny plasma ruptures, shock waves, thermal stress, etc., causing surface materials to sublimate and evaporate.

The laser beam can be precisely positioned on the surface of the material to be cleaned, can clean irregular or more concealed surfaces. The machine will remove all rusts and impurities off any metallic surface.
In 1962, Robert N. Hall demonstrated the first laser diode device, which was made of gallium arsenide and emitted in the near-infrared band of the spectrum at 850 nm. Later that year, Nick Holonyak, Jr. demonstrated the first semiconductor laser with a visible emission. This first semiconductor laser could only be used in pulsed-beam operation, and when cooled to liquid nitrogen temperatures . In 1970, Zhores Alferov, in the USSR, and Izuo Hayashi and Morton Panish of Bell Telephone Laboratories also independently developed room-temperature, continual-operation diode lasers, using the heterojunction structure.
