Interference patterning on glass with sub-micrometre structure spacing.

A new setup for Direct Laser Interference Patterning DLIP enables the functionalization of glass surfaces at sub-micro level. Tailored spatial periods with periodic patterns down to 200 nm show amazing optical effects for anti-counterfeiting without using color pigments or enable spatial alignment of cell elongation of pluripotent stem cells.
