A secondary low-power laser helps to visualize the main laser’s alignment without actually cutting the target. There are a couple of ways to install an aiming system like this, but which way ...

We hate to admit it, but laser cutter beam alignment is no easy task. To greatly assist in this endeavor, though, some folks tend to mix a red diode laser into the path of the beam. Others ...

Laser cutters ... thinks the test pattern is versus its scan. Nudge the overlay around until everything is perfectly stacked, and you’re set. You’ll want to re-run this alignment process ...

Laser cutting machines are becoming an essential tool offering precision and versatility to entrepreneurs, manufacturers and ...

Laser cutting works by directing a laser together with a motion control system to follow a pattern to be cut out of a sheet of material. The laser either melts, burns, vaporizes away the material, or ...

In this paper we evaluate the use of picosecond laser acoustics (PLA) measurement as an alternative method to characterize the overlay and alignment patterns that are embedded under opaque metal films ...
