About 10.2 µm CO2 Laser Wavelength

Did you know CO2 lasers are commonly found in three wavelengths? 10.6 µm is the most popular and performs well for most applications. 9.3 µm and 10.2 µm are used to process special materials like Polyethylene Terepthalate (PET) or Polypropylene (PP) based on their specific absorption spectrum. Each of these materials has a characteristic absorption spectrum, meaning there are certain wavelengths of light a given material will absorb more readily than others, enabling better laser processing results.

Why Laser Wavelength Matters


Lasers can be used for a variety of processes—including cutting, marking, and scoring—on materials we use daily. Why does this matter? Lasers produce light at very specific wavelengths. By pairing that wavelength to a material that easily absorbs it, the application results are of higher quality and the processing itself is faster.

Polypropylene (PP) coated paperboard marked with 10.6 µm and 10.2 µm wavelength lasers yielded these results -

10.6 µm: Legible, but the mark is inconsistent.


10.2 Glossy Paperboard Mark Inset

10.2 µm: Clean, consistent, and highly visible

Why Laser Wavelength Matters


Flex Packaging Inset

This wavelength has improved absorption in Polypropylene, allowing better application quality and faster throughput. 10.2 µm can also be used to process standard materials like paper, plastics, fabrics, and cardboard. Since Polypropylene is commonly found in the packaging, labeling, nonwovens, and industrial manufacturing industries, common applications include:
