Gaussian or top-hat: which beam profile for laser cleaning?
Two beam profiles, two removal patterns. Where the top-hat profile has its strengths, where a Gaussian beam is enough, and what to consider when choosing.
Why protective lenses get dirty and crack
The protective lens shields the expensive optics and wears out in the process. Causes of contamination and cracks, and what helps in practice.
How to maintain a laser cleaning system properly
A laser cleaning system runs reliably when optics, fiber cable and cooling are checked regularly. This article shows what the operator handles and what belongs to the manufacturer.
Cheap lasers from China: what the low price really costs
Laser cleaning systems from the Far East lure buyers with rock-bottom prices. What is behind them, who is liable if conformity is missing, and why the purchase price is only…
Why dark coatings are removed faster by laser
Dark paints can often be removed faster with a laser. What matters is absorption at 1064 nm, not the color the eye sees.
