Laser Beam Interference Ablation

Laser  Beam  Interference  Ablation  (LBIA)  combines  multiple  laser  beams  to  create  a  spatial interference pattern. The interference effect allows reducing feature dimensions to below the diffraction limit, Multi-beam parallel processing for periodic structures.

LBIA is  used for 2D patterning of thin films and surfaces and surface modification. Min period 600 nm using 532 nm wavelength, with uniform spacing within the laser spot size  of ~50um


Tested materials:

Absorbing surface required: Chromed glass, Au, Cu, Si, Al, others
