The carbon dioxide (CO2) laser is the most popular laser marker. With the lowest price tag and minimal maintenance requirements, it has become the industrial laser marking leader.
When laser marking wood, plastics, some rubber types, and other nonmetals, the CO2 laser provides a solid laser mark. The laser beam diameter is much larger, about ten times, that of the fiber and lamp pump lasers. The result is a thicker line that penetrates the material quickly and effectively.
The CO2 laser marking machinery is commonly used in the fields of automobile parts marking, crafts, nameplates, construction parts marking, ceramics, and pharmaceutical packaging.
When choosing your laser work station below, be sure to consider the marking area (4" or 6" square, etc.). Choose the smallest area that meets your needs, in order to gain the finest clarity laser beam within the specified area.
Also, your laser power affects your maximum laser marking speed. You cannot go wrong by selecting a higher power laser, then using the computer to decrease the laser power for a specific part, if required.
The CO2 laser marking work station provides 30 watts of laser power for marking.

The CO2 Laser Marking Work Station, with 150 watts of power is capable of laser marking a much larger area. As the laser source is quite far above the material, the increased laser power is required to effectively mark the material with a larger laser spot. In other words, the energy density remains the same as the smaller laser with the tinier spot size. As a result, this laser is often used to laser mark large areas, or even laser cut paper or textiles. Also, available in 100 watts, contact us for specification.

The CO2 laser beam profile is gaussian in shape, with the most energy in the center. This enables laser marking at different line widths, depending upon the speed setting. CO2 lasers operate at the highest wavelength, more than ten times the diameter of fiber, diode, and lamp pump lasers. Also, the CO2 is simplest and least costly to construct, thus making them the most popular industrial lasers.
CO2 lasers typically mark nonmetal products that can accept a heat affected zone when marking. These materials include plastics, wood, rubber, electrical components (other than metal), and more.
