It offers these benefits as it works in a significantly different way to the processes that have preceded it. Furthermore, using a fiber laser as the medium also works in a much different way to other types of cleaning methods. They provide a more controlled process that does not accidentally damage a surface through excessive removal, and can also be used on thin and composite materials that would be damaged by the particle impact. Fiber laser cleaning is always consistent, independent of operator effects, and can scale to suit the job size by selection of the laser power. Besides, we can provide users with fiber laser cutters, co2 laser engraving machine, laser marking machine as well as CNC routers.
Compared with the traditional way, it has the advantages of environmental protection, no grinding , no thermal effect etc, and has unique advantages in cleaning precision workpiece.

If you need to increase surface adherence or friction to prepare surfaces, you may need laser texturing, a surface treatment similar to laser cleaning.
The technology drives higher process efficiency and reduced residual heating of the substrate material. This laser process deburrs, rounds, and strengthens the edge of sheet metal. Sensor manufacturer Crocus Technology is among the first to install the new system for production applications. Cleaning performance comparison on carbon steel by CW and MOPA pulsed fiber laser . Cleaning performance comparison on aluminum by CW and MOPA pulsed fiber laser . FIGURES 1 and 2 show the cleaning performance by the test lasers detailed in the TABLE.
The way to overcome this problem was to charge up large capacitors which are then switched to discharge through flashlamps, producing an intense flash. Pulsed pumping is also required for three-level lasers in which the lower energy level rapidly becomes highly populated preventing further lasing until those atoms relax to the ground state. These lasers, such as the excimer laser and the copper vapor laser, can never be operated in CW mode. In a Q-switched laser, the population inversion is allowed to build up by introducing loss inside the resonator which exceeds the gain of the medium; this can also be described as a reduction of the quality factor or ‘Q’ of the cavity. This results in a short pulse incorporating that energy, and thus a high peak power. The optical bandwidth of a pulse cannot be narrower than the reciprocal of the pulse width.

Microscopic surface after cleaning on aluminum by CW and MOPA pulsed fiber laser . With a CW fiber laser, the slower the scanning speed is, the greater the damage to the substrate. However, when the speed is higher than the threshold, a faster speed will cause insufficient cleaning. Thus when using the CW fiber laser to perform laser cleaning, it’s critical to choose the right scanning speed. Laser engraving machine is mainly used for processing non-metallic materials such as acrylic, wood, rubber and some thin metal plates. Laser cutting machine is mainly used to process metal material such as stainless steel, carbon steel, and galvanized sheet, etc.
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.
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 heterostructure nanowire lasers capable of optical interconnects in silicon are also capable of emitting pairs of phase-locked picosecond pulses with a repetition frequency up to 200 GHz, allowing for on-chip optical signal processing. Another type is a Raman laser, which takes advantage of Raman scattering to produce a laser from materials such as silicon. In other cases, the application requires the production of pulses having as large an energy as possible. Since the pulse energy is equal to the average power divided by the repetition rate, this goal can sometimes be satisfied by lowering the rate of pulses so that more energy can be built up in between pulses. Particular applications may require further spatiotemporal intensity distribution through the use of a dual-spot module, trifocal beam delivery, beam wobbling, or adjustable mode beam solutions. AMB lasers feature a coaxial ring around a fiber laser’s inner core.
It has been humorously noted that the acronym LOSER, for “light oscillation by stimulated emission of radiation”, would have been more correct. With the widespread use of the original acronym as a common noun, optical amplifiers have come to be referred to as “laser amplifiers”, notwithstanding the apparent redundancy in that designation. Fiber lasers can be classified by several operation modes, including continuous wave , quasi-CW , nanosecond pulsed, and ultrafast pico- or femtosecond pulsed.

A coherent beam of light is formed by single-frequency quantum photon states distributed according to a Poisson distribution. As a result, the arrival rate of photons in a laser beam is described by Poisson statistics. For the gain medium to amplify light, it needs to be supplied with energy in a process called pumping. The energy is typically supplied as an electric current or as light at a different wavelength. The back-formed verb to lase is frequently used in the field, meaning “to produce laser light,” especially in reference to the gain medium of a laser; when a laser is operating it is said to be “lasing”.
