Medical CO2 lasers are high-powered laser devices used for a wide range of medical procedures. They use a carbon dioxide gas mixture as the active medium and emit light in the mid-infrared range. These lasers are capable of delivering intense beams of light that can be precisely focused to perform a variety of medical applications, including skin resurfacing, scar revision, wrinkle reduction, and treatment of vascular and pigmented lesions. They can also be used for surgical procedures, such as cutting, ablation, and coagulation of tissues. Medical CO2 lasers are generally considered safe and effective when used by trained medical professionals, and their use is regulated by various government agencies to ensure patient safety.
