What are CO2 and Thulium lasers? 1.Definition of CO2 laser CO2 laser is a kind of gas laser, which uses carbon dioxide (CO2) as the activation medium. It operates at a wavelength of 10,600 nm, which is primarily absorbed by water in the skin. This makes it highly effective for ablative and micro-ablative treatments, where it creates controlled thermal damage to stimulate collagen production and skin renewal. 2.Definition of technetium laser On the other hand, Thulium laser is a kind of solid-state laser, and its working wavelengths is 1,927 nm or 1,940 nm. It emits long pulse infrared light, aiming at water, melanin and hemoglobin in the skin. Unlike carbon dioxide lasers, Thulium lasers are non-ablative, which means that they heat the deep layers of the skin without removing the surface layer, thus reducing downtime and speeding up recovery.
