Laser Marking
Cold marking with picosecond pulses
Video courtesy of ACI Laser.
Overview
Business Fiber Ultra Short Pulse combines high pulse power with a pulse duration in the picosecond range, which means it marks without putting heat into the part — cold marking. Detail resolves in the micrometre range and the surrounding material is left essentially undamaged, so it suits medical components, thin coatings and other parts a conventional fibre laser would distort or discolour.

Ratings published by ACI Laser for each model in this series.
Every ACI system is driven by Magic Mark, the supplier's own marking software. It handles text, graphics, barcodes and Data Matrix codes, serial numbers and logos, and will mark right around a cylindrical part without a rotary attachment.
Operator permissions are set per user group, so a machine on the shop floor can be locked to running jobs while programming stays with the people who own it. On an automated line Magic Mark runs unattended and exchanges job data with your existing systems; plug-ins add code generation and scripting where a process needs them.
The laser itself is a Class 4 device. Its safety circuit is certified to EN ISO 13849 at Performance Level e, Category 4 — the highest level in the standard — so a fault brings the system to a safe state rather than an uncertain one.
Installed in one of the laser stations, the whole system becomes Class 1: safe to stand at, with no additional screens, interlocks or eyewear to manage. That is the usual arrangement for a manual marking bay, and the reason most of these lasers are quoted together with a station.
A Class 4 laser is normally supplied inside a station, which makes the installation Class 1 and ready to use. These are the stations this system can be fitted to.
