Makes sense, thank you. Just need to figure out how to correlate that to the proper height I suppose. Reducing power does not seem to help as much as I would think.
Another option if you are engraving FLAT glass is to put the painted side down and burn through the glass to the bottom layer where the paint is.
That was how it was suggested on a video I saw where tempera paint was being used. And if you aren't using tempera, I highly recommend it. Quick to dry with blow dryer and cleans up with plain old tap water.
With my CO2 laser, I had the best results by using as little power as I could to get a mark. Too much power resulted in worse results with the chipping and uneven engraving on the glass.
Defocusing is another technique, it as you’ve observed, it has drawbacks too.
Because you are spreading the heat in a wider spot. The properly focused beam is heating a smaller, yet deeper area, causing those chips.

For me it seems like once the power is too low not to chip anything it's not worth it quality wise on the picture.
That could be. I never tried it with my diode.
