A carbon dioxide laser is a type of gas laser that uses carbon dioxide as its active medium. It produces a high-intensity beam of infrared light, which is invisible to the human eye. This laser is commonly used in various applications, including industrial cutting, welding, and medical procedures due to its ability to efficiently cut and vaporize materials. The carbon dioxide laser operates by exciting carbon dioxide molecules with electrical energy, causing them to emit photons. These photons are then amplified to create a powerful laser beam. Its effectiveness in cutting and engraving makes it a popular choice in manufacturing and surgical settings.
