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:
- Dust free
- High 3D resolution
- Colour variation
- Variation in index up to 0.01 depending on the materials
- Precision of 1 μm in XYZ directions
- Custom 3D patterns
- Processing speed: up to 100 mm.s-1 for index change
- Colouring process speed: 1.5 m.s-1
- Pulses: femtosecond, picosecond and nanosecond
- Wavelengths: infrared and visible
- Numerical aperture from 0.2 to 0.4
- DXF, JPEG implementation
Materials used for intra-volume marking:
- Organic glass
- Doped glass
- Industrial glass
Areas of application
- Phase mask
- Optical microscopy
- Ophthalmic optics
- Bottle making

Selective ablationThe 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 ablationLaser engraving is carried out by removing material layer by layer to obtain a 2D or 3D effect on all material types.
Laser shock peeningShock waves (> GPa) applied to metallic materials improve their fatigue resistance and their resistance to corrosion.
Machining of transparent materialsCutting, 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 drillingLaser 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 cuttingLaser cutting enables precision part production of all material types, even of transparent and hard materials such as SIC and diamond.
Surface texturingLaser texturing and surface functionalization make it possible to create effects or generate new properties on all surface types.
