As the output power of the Co2 laser is getting higher throughout the years, the technical demands and damage threshold the Co2 laser optics need to withstand is more challenging. As a solution to those challenges optics manufacturers added cooling system to the Co2 laser Cu mirror, by that the mirror will be less inclined to thermal expansion, and a proper cooling of the optical surface is ensured. The cooling of the Co2 laser optic surface is achieved by drilling of channels close to the surface, by that there is less damage to the coating as in is exposed to less heat. This drilling is not applicable to Si mirrors due to the brittleness of the material.
