Laser Nano-Structuring: Adding Colors or Trapping Light

or: The Wind of Light


Ferrum 90/2018 

We don’t see light through the air; we can only see the obstacles it encounters. In fact, our perception is all about collisions. Our vision itself begins with collision on the surface of our eyes and ends with the mind construct we call reality. Let’s then play with the nanostructure of the surfaces. This article will briefly describe the major steps in developing a machine using laser to structure 3-D surfaces and then present the different attempts in adding colors by light by reflection as well as light trapping.
