RDWorks Learning Lab 211 Understanding Black Etching Ceramics Pt1

The popularity of the 450nm blue diode laser has created a lot of interest in etching images onto ceramic tiles.There may be similarities between the physics/chemistry of this new technique and the LaserTiles that I tested about 3 years ago, but I was never able to decode the vital facts that underpinned the Laser Tile magic. With several failed emulation attempts in my history book , I lost interest about a year ago. However, my new enthusiasm for this subject has been prompted by people wanting to add a CO2 laser machine to their hobby inventory after starting small with a blue diode laser. I keep being questioned about whether the CO2 laser can perform this same black etching onto ceramics. The 450nm wavelength light has significantly different capabilities to the 10,600nm CO2 wavelength, so there is no simple yes/no answer I can give. I have already demonstrated failure, but now there are a few more clues that I can examine from the successful diode laser method. Anyone familiar with my learning journey will realize that I will not be interested in a tedious hunt for parameters that may or may not be there. I need to understand the mechanism that allows the blue diode to be successful at this task. Only when I possess that knowledge will I be able to answer the question.
