Technical Notes

Short, practical notes on laser marking engineering — wavelength choice, speed, optics and process effects. Written to help you reason about the machine before you send samples.

Notes — Technical Series

From wavelength choice to process tuning.

Fiber vs CO₂: How to Choose the Right Wavelength

The dividing line between a 1064 nm fiber and a 10.6 µm CO₂ is the material — metals absorb the near-infrared, organics absorb the far-infrared. A quick decision rule before you test samples.

Understanding Marking Speed and Throughput

Scanner speed in mm/s is not parts-per-minute. What actually drives cycle time — mark area, passes, power density and loading — and how to read the real throughput from a sample test.

Lens and Marking Area: Matching the F-Theta Field

Why a wider field lowers resolution and raises working distance, and how to pick between the standard F160, F254, F330 and F420 fields for your largest workpiece.

Why MOPA Makes Color Marking on Anodized Aluminum Possible

MOPA sources can offer broader pulse-width control than many Q-switched sources. Suitable stainless steel and titanium can develop oxide colors; selected anodized aluminum can produce dark or contrasting marks. Source limits, material condition and process settings determine the result and repeatability.

UV Cold Marking: When Heat Becomes the Problem

On plastics, glass and coated parts, heat is the enemy. A 355 nm UV beam breaks molecular bonds instead of melting material — keeping the heat-affected zone microscopic and the edges sharp.

Variable Data: Serial Numbers, QR and DataMatrix for Traceability

How sequential numbering, date/time stamps and machine-readable codes are generated and updated automatically in the marking software for traceability runs. Ask an engineer for the parameters that suit your part.
