Intra-volume marking by laser allows a very local modification of the refractive index in transparent materials. This modification allows an inscription of patterns in 3D to functionalise or create a decorative effect in the material.
The characteristics of the intra-volume marking process:
- No dust
- High 3D resolution
- Colouring for doped glasses
- Refractive index change up to 0.01 depending on the materials
- Precision 1 μm in XYZ
- Customized 3D patterns
- Processing speed: up to 100 mm.s-1 for index change
- Process speed for colouring: 1.5 m.s-1
- Pulse duration: femtosecond, picosecond and nanosecond
- Wavelengths: infrared and visible
- Numerical aperture from 0.2 to 0.4
- DXF, JPEG implementation
The transparent materials concerned:
- Organic glass
- Doped glass
- Industrial glass
- Phase mask
- Optical microscopy
- Ophthalmic optics

Laser shock peeningThe laser shock peening process improves fatigue and corrosion resistance through the use of shock waves greater than GPa on metallic materials.
Machining of transparent materialsThe machining of transparent materials consists in cutting, welding, drilling and engraving by minimising mechanical stresses.
Laser drillingLaser drilling allows you to obtain holes of variable geometry with a large aspect ratio, crossing or not all types of materials and all thicknesses.
Laser cuttingLaser cutting allows the manufacture of precision parts from all types of materials, even transparent and hard, like silicon carbide or diamond.
Surface texturingSurface functionalisation or texturing by laser allows you to create effects or give new properties to all types of materials, according to the desired function.
