…of plastics which produces a raised mark by deliberately creating a type of recast material on the surface or surface removal where a top layer of a lacquer or paint is removed to reveal a substrate of a different color or reflectivity underneath. Wood and other organics are sometimes marked by…

…laser marked products, this
HAZ doesn't represent a significant problem.
With a picosecond laser, the laser processed material is
removed in such a short timeframe that the vaporized
material carries away any heat before it can spread.
However, in some applications, even a…
mold release agent. The SEM photos (FIGURE 3) demonstrate the technique's ability for highly controlled
bond and matrix material removal
without damage to the exposed fbers.
After laser cleaning, specimens
were bonded, and bond strength was

…applications rely on infrared
and visible Q-switched lasers, which have
pulse widths in the tens of nanoseconds
range, and which remove material via a
photothermal interaction. Here, the focused
laser beam acts as a spatially confined, intense
heat source. Targeted…

…PMMA. The homogenized excimer beam is passed through a photomask, which is then re-imaged on this coated substrate. The high energy UV photons interact with the metal/substrate interface, directly removing the thin metal film in a pattern defined by the mask image. With a metal film thickness of 40…
…quality makes the HighLight FL1000P an ideal laser source for ablation, surface cleaning, and precision material and coating removal in a range of applications. These include AlSi removal from tailored blanks prior to welding, edge deletion for thin film (a-Si, CdTe, CIGS) solar cells, cleaning of…
Fiber-laser-based machine vision solutions offer versatility and improved line resolutions for industrial uses.
This is a prototype demonstration of a machine-vision-controlled laser-based selective coating removal

…only after non-contact methods have failed. Some optics
have a special anti-reflective coating. Using a cleanser (such as isopropyl alcohol)
to remove contamination can damage this coating and the optical lens assemblies.
If your laser generates a pattern requiring…

8. At this point you should put on gloves or at the very least a glove on your left hand. The optic window should
never be handled with bare fingers. The most important point to remember is that the optic window has a very
delicate coating that must be protected.…
