Intra-volume marking
Intra-volume marking with the laser makes it possible to locally modify the refractive index of transparent materials. This modification allows you to inscribe 3D patterns to functionalize or to create a decorative effect in the material.
The characteristics of the intra-volume marking process:
Benefits
- Localized
- Dust free
- High 3D resolution
- Colour variation
Performance
- Variation in index up to 0.01 depending on the materials
- Precision of 1 μm in XYZ directions
- Custom 3D patterns
Throughput
- Processing speed: up to 100 mm.s-1 for index change
- Colouring process speed: 1.5 m.s-1
Laser workstation
- Pulses: femtosecond, picosecond and nanosecond
- Wavelengths: infrared and visible
- Numerical aperture from 0.2 to 0.4

Selective ablation
The use of a specific pulse duration and/or suitable wavelength(s) makes it possible to work in a condition where the surface layer ablation threshold is lower than the substrate’s. -
Etching - Controlled ablation
Laser engraving is carried out by removing material layer by layer to obtain a 2D or 3D effect on all material types. -
Laser shock peening
Shock waves (> GPa) applied to metallic materials improve their fatigue resistance and their resistance to corrosion. -
Machining of transparent materials
Cutting, welding, drilling and engraving of transparent materials with minimization of mechanical stress. Short or ultra-short pulse lasers allow transparent materials to be machined with or without removal of material and to modify their intra-volume physical properties. -
Laser drilling
Laser drilling makes it possible to create through or blind holes with variable shape and high aspect ratio, on all types of materials and thicknesses. -
Laser cutting
Laser cutting enables precision part production of all material types, even of transparent and hard materials such as SIC and diamond. -
Surface texturing
Laser texturing and surface functionalization make it possible to create effects or generate new properties on all surface types.
