Case Studies: Pulse Duration in Real-World Applications
Case Study 1: Optimizing Laser Pulse Duration for Marking on Anodized Aluminum
When marking anodized aluminum, selecting the right pulse duration is essential to avoid damaging the anodized layer while achieving a sharp, high-contrast mark. In one application, using a pulse duration of around 20 nanoseconds allowed for a clean, precise engraving without affecting the integrity of the anodized surface. This pulse duration delivered just the right amount of energy to create a deep, durable mark, perfect for logos or serial numbers without causing any surface charring or distortion.
Case Study: Color Marking on Stainless Steel with a MOPA Laser
Using a MOPA laser with adjustable pulse duration, vibrant color markings were created on stainless steel without the need for coatings or chemicals. A pulse duration of around 200 nanoseconds enabled precise heat control, altering the surface oxide layer to produce colors like blue, green, and red, while preserving the material’s integrity.
This method delivered durable, sharp color marks, ideal for industries like luxury goods and electronics where aesthetics and branding are key. The flexibility of the MOPA laser provides both functional and decorative marking options with precision.
