Introduction to the project
Objectives
Developing a new laser in the UV range
Adapting existing materials for having a better beam absorption
Integrating the laser in the industrial process
Developing a user application for demonstrating the unitary customization with real customers
IR
UV PP
Project Background
Laser:
Frequency of pulses, velocity, fluence (energy/area), number of runs, distance lens-
sample, time of pulse, wavelength…
Interaction laser/matter depends on:
Absorption at the laser wavelength, composition, internal microstructure,
mechanical properties, thermal properties, fillers…

Project Background
■ Interaction between light and matter depends on the wavelength
■ Important laser parameters − Pulse duration − Pulse energy − Velocity − Beam quality
■ Material absorption determines the degree of interaction

Features
Project Background
Engraving and ablation – For engraving, the laser beam removes the material.
– Ablation is the partial removal of coating layers from the base material.
– Application for most materials (metals, plastics, ceramics…)
Annealing – Oxidation. Black colors
– Annealed markings can be generated by using the laser beam to heat the work piece to a certain temperature where the marking should appear. This creates oxide layers on the surface whose composition determines the colored appearance.
– For ferrous metals and titanium
Coloring and foaming. Chemical reaction – Foaming. White marks
– Carbonization. Black marks
– Photochemical reaction. Any color
– For plastics only
Project Background
An electro-magnetic wave is generated by a laser-active medium (Neodym, CO2, ..)
The amplified beam is deflected to the marking area.
The size of the marking area depends on the distance between the lens and the marking surface (the larger the focal distance, the bigger the marking area).
Irradiance is very important

Project Background
Comparison of a topographic profile of a transverse cut of samples UV and green, represented with the same scale. It appreciates that the hurt in the material is very much minor, and surface presents a more homogeneous appearance
