Carbon monoxide (CO) lasers are for materials processing applications ranging from glass cutting and via drilling, to fractional skin resurfacing. Output at a wavelength of approximately 5µm; strong absorption in certain plastic films, polymers and water, as well as some dielectric materials and copper oxides used in printed circuit boards. Have low absorption in chalcogenide fibers. Focus to spot size 2x smaller than the CO₂ laser. J-35µm outputs over 200W. Has high quality beam (M² < 1.2). CO lasers reportedly have similar lifetime, reliability and maintenance characteristics as slab discharge CO₂ lasers.
