Laser micro-texturing

By laser microstructuration, we mean:

the use of a laser in order to directly modify the surface or the bulk of a material.
Several types of laser can be used for these highly valuable applications.

• 

  Nozzle for CLAD (Direct additive laser construction) (with IREPA Laser)

• 

  Super-hydrophobic surface (right) on PDMS obtained by laser micro-texturation (with IREPA Laser)

• 

  Rainbow colored effect on stainless steel by laser micro-texturation (with IREPA Laser)

• 

  Femtosecond laser marking in bulk glass (with IREPA Laser)

Our work focuses on:

• micro-structuration by femtosecond laser
• surface fonctionnalization by laser micro-texturation (wettability, self-cleaning, biocompatibility)
• 3D metallic additive construction.

We have recently obtained:

• color effect on different materials by the creation of RIPPLES
• creation of hydrophobic and hydrodrophilic surface on stainless steel and PDMS
• complex 3D geometric shapes printing by direct additive laser construction (BeAM society: the CLAD direct additive laser construction video).
