When cleaning the dust on the aluminum alloy, the cleaning efficiency of the MOPA pulsed fiber laser is 2.77 m2/h, which is 7.7X the cleaning efficiency by a CW fiber laser (0.36 m2/h). When cleaning the dust on the carbon steel, the cleaning efficiency of the MOPA pulsed fiber laser is 1.06 m2/h, which is 3.5X the cleaning efficiency of the CW fiber laser (0.3 m2/h). Handling and disposal of hazardous chemical solvents is eliminated by laser cleaning. The reduction in costs of consumable solvents and the expensive requirements for post process treatment and disposal of these chemicals are not a factor for laser cleaning, making it both the environmentally preferred and lowest cost solution.
Laser cleaning is a non-contact process that generates almost no maintenance , consumes little power and can be completely automated to provide a big return on investment. Laser welding creates oxide byproducts that prevent passivation and give a bad appearance. You can address both issues with laser surface cleaning, which ensures that welding joints are oxide free in just a few seconds. The CleanTech™ Handheld NCX is a complete industrial-grade, rugged, high precision portable laser surface cleaning and conditioning system.
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.
We started to make engraving lasers in Warsaw, Poland in 2014 after being awarded at the “Best Polish Start-Up” competition. We can deliver complete solutions within a short timeframe due to our unique capabilities. We operate a full-time production-grade CNC mill in our machine shop, which allows us to move from a concept to the product in a short time and control the entire design and production process. Our team designs own electronic components specifically for particular products to maximize performance and reduce costs. Looking into the growing needs of the sheet metal industry Scantech was established in the year 1991 for manufacturing laser marking machines, and since then we have not looked back. Scantech is into wide variety of laser applications in diverse fields like automobiles, medical, pharmaceuticals, electronics, semiconductors, fabrication and many others.
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.
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.
