The Norton method to permanently etch ceramic tile with a 2.5w diode laser.
1. I am not Nicky Norton. I posted the video for him so he could send people the link. It is not my technique, I learned it from Nicky.
2. YOU MUST HAVE A 1.8WATT OR 2.5WATT LASER WITH AN UPGRADED LENS OR YOU WILL NOT ACCOMPLISH THIS TECHNIQUE. IT IS 100% DEPENDANT UPON ABSOLUTE PERFECT FOCUS.
YOU CAN NOT DO IT WITH A 5.5WATT OR 7W LASER, THEIR DOT SIZE IS TOO LARGE.
3. Even if you have the 1.8w or 2.5w and an upgraded lens, there is no guarantee that you will be successful. Technically it should be impossible to affect the ceramic with a diode laser.

( There is no such thing as a diode laser that has a native power of over 7.2 watts. Companies like Endurance laser overpower diodes and add heatsinks trying to cheat the limit. Less honest ones will list the wattage of the power supply trying to scam you into believing you are getting something you aren't.)
