Er:YAG laser

You have the CO2 laser operating it at a wavelength of 10,600 nanometers.

and the Erbium.YAG laser operating at 2,940 nanometers.

Now the CO2 lasers are the older technology, right? How does that one interact with the tissue?

The CO2 laser is what we call fractional microablative.

Right, right.

That's a very common misconception.

Yeah, but the Erbium.YAG operates in a completely different mode, specifically a non-ablative smooth mode, right? It's not punching microscopic holes in the tissue or vaporizing anything.

Exactly.
