![]() A laser-driven manufacturing process must deliver sufficient laser power to the work area at the correct time. The single most important factor in CO 2 laser processing is the beam quality. Each gas plays an independent role in the total process and is critical to a successful operation. ![]() The exact mixture will vary according to the design, operating pressure, and operating mode selected by the laser system's manufacturer.īesides generating the laser beam, gases are used to protect the transmission of the beam from the resonator to the workpiece and also to cut the material ( Figure 1). In some cases, other gases may be added to the mixture. In the CO 2 laser process, the beam is produced by exciting a mixture of carbon dioxide, nitrogen, and helium. In fact the word laser is an acronym for light amplification by stimulated emission of radiation. The laser beam is nothing more than light. The CO 2 laser process depends on the power of the laser beam produced. ![]() New laser technology that produces cutting systems with higher power, improved material handling, and on-time monitoring will meet future market demands and encourage laser processing growth. A process's growth depends on how the technology and its ancillary components serve the user. Although continuous improvements have been made to increase CO 2 laser cutting productivity, the basic parameters of the process have not changed in the last 20-plus years.
