Understanding the relationship between laser power, material thickness, and cutting speed is essential for optimizing CO2 laser cutting operations. This comprehensive guide provides detailed cutting parameter charts for common materials, explains the factors affecting cutting performance, and offers practical guidance for selecting optimal settings.
CO2 laser cutting relies on focused infrared laser energy (10.6 micron wavelength) to melt, burn, or vaporize materials along programmed cutting paths. The three critical parameters—laser power, material thickness, and cutting speed—interact to determine cut quality, edge finish, and production efficiency. Proper parameter selection ensures clean cuts, minimal heat-affected zones, and maximum productivity.

CO2 Laser Cutting
CO2 lasers can cut through materials of varying thicknesses at various speeds, depending on laser power, as well as material type and hardness. Higher power lasers are capable of cutting thicker materials at faster speeds. In most cases, CO2 laser cutters work with a power range of 40 watts to 300 watts to cut through wood with a thickness of 1 mm to 20 mm at a speed of 1000 mm/min to 9000 mm/min, acrylic with a maximum thickness of 40 mm at a speed of around 1200 mm/min, leather and cloth with a thickness of 0.75 mm to 10 mm at a speed of 500 mm/min to 12000 mm/min, and paper with a thickness of 0.5 mm to 11 mm at a speed of about 3000 mm/min.
Three core parameters determine cutting performance:
-
Laser Power (Wattage)
-
Material Thickness
-
Cutting Speed
These parameters are closely connected. Higher laser power allows thicker materials to be cut at higher speeds, while lower power requires slower speeds or thinner materials to achieve clean cuts.
CO2 Laser Power Explained
Laser power is measured in watts (W) and represents the energy output of the laser tube.
Common CO2 laser power levels include:
-
40W–60W: Entry-level machines for thin materials, engraving, and light cutting
-
80W–100W: Popular mid-range power for small workshops and signage production
-
130W–150W: Industrial-grade cutting for thicker acrylic and wood
-
200W+: Heavy-duty CO2 laser systems for high-speed, thick material cutting
Higher power does not always mean better results. The ideal power depends on material type, thickness, and production volume.
CO2 Laser Power, Thickness, and Speed Relationship
A simple rule applies:
Higher laser power = thicker cutting capability or faster cutting speed
However, optimal results come from balancing all three parameters. Increasing power without adjusting speed may reduce edge quality, while slowing speed too much can overheat the material.
Other important factors include:
-
Lens focal length
-
Air or gas assist pressure
-
Laser tube quality
-
Machine stability and motion system
