Medical device marking with femtosecond lasers is a high-precision method used to permanently mark medical devices with critical information, such as serial numbers, barcodes, logos, or other identifiers. Femtosecond lasers emit ultra-short pulses of laser energy that interact with the material surface without generating significant heat. This technique is especially valuable for marking sensitive materials, such as metals, ceramics, and polymers commonly used in medical devices.

The marks produced by femtosecond lasers do not introduce contaminants or negatively impact the material, maintaining the biocompatibility required for medical devices. The marks are permanent and resistant to wear, sterilization, and harsh environments – essential for devices that undergo repeated use and exposure to medical cleaning processes.

Overall, femtosecond laser marking ensures that medical devices meet regulatory standards while maintaining functionality and patient safety.

Black and white marking with femtosecond lasers refers to the process of creating high-contrast, durable markings on materials by adjusting the interaction between the laser pulses and the surface. Femtosecond lasers can produce precise markings without causing significant heat damage, making them ideal for marking delicate or sensitive materials.

In black marking, the femtosecond laser modifies the surface by altering its structure at a microscopic level. This creates a dark appearance, often through localized oxidation or nanostructuring, without adding any pigments. This technique is commonly used for marking metals like stainless steel, where deep, black marks are desired for contrast and legibility.

In white marking, the laser causes a different interaction with the material, typically by inducing surface modifications or controlled ablation to create a lighter, frosted appearance. This type of marking is often used for darker materials or when a high contrast against a dark background is needed.

Femtosecond lasers offer improved quality compared to picosecond or nanosecond lasers and expand the number of materials that can undergo high-contrast marking. This process allows deep engraving, medical instrument marking, hidden marking, and counterfeit marking on glass, plastics, metals, and ceramics. Corrosion-free marking is also achievable on stainless steel.

Both PHAROS and CARBIDE femtosecond lasers, equipped with BiBurst, are the optimal choice for versatile high-contrast marking.
