The decision to select a fiber laser or a CO2 laser will be determined primarily by what materials you need to mark. While a fiber laser will mark bare metals, ceramics and engineered plastics, a CO2 laser system can engrave on a wider variety of materials, including wood, acrylic, rubber, plastic and more.

Carbon dioxide lasers are gas lasers which emit infrared radiation. They are used for a variety of high power industrial applications. As discussed in the Lasers Selection Guide, all lasers consist of three components: an energy source (also known as a pump), a gain (or laser) medium, and an optical components are labeled in the diagram below.

Metal vs. Organic. CO 2 lasers with power levels below W produce energy that is easily absorbed by most organic materials, but is mostly reflected by metals at room temperature. While CO 2 lasers can mark, cut and engrave organic materials, marking on metals is only possible using specialized optics or marking compounds.
