The paint on tile is the original Norton Tile Method (NTM) that you read about… Heat causes the molecular bonding of the TiO2 to the glass… It works on other materials also…
What most of us don’t like is dealing with solvents to remove the unwanted paint after lasing. A lot of us have tried to use water or other non-volitile or toxic types of coatings to try this without the problems of solvents…
My co2 and my fiber both reside within the IR region… this is very broad… the co2 will not work on metals without a coating, but the fiber has no problem… Both are IR, but the fiber frequency is 100 times the frequency of the co2.
Yours and most are diode-pumped solid-state laser (DPSSL) lasers that are basic Nd:YAG types… with an output around 1064nM.
You can see Nd:YAG frequency on the chart compared to co2.
Most of the ss led types I’ve seen in the ir spectrum are in the 1064nm frequency, which is similar to the fiber.
Nice work, thanks for posting…
@Bulldog does magical work with these… he’s using a fiber, but it’s the same frequency as your ir… he’s got a bit more power available… but you should eyeball his work…
Have fun
