What is the difference between CO2 laser and other lasers in the processing process?

Different wavelengths of lasers interact with materials in different ways, and some applications are well suited for processing with a CO2 laser, while others may work better with other lasers.

Compared to CO2 lasers, lasers with shorter wavelengths can usually be focused to a smaller spot, resulting in higher power densities on the workpiece and, in theory, faster processing speeds. But this advantage doesn't work when there are materials that don't absorb shorter wavelengths well.

The effect of laser marking can be completely different at different wavelengths, depending on the material itself. CO2 lasers put a lot of heat into the material, so the heat-affected zone is very important in some applications; however, in many cases, CO2 lasers are still the most efficient technology.
