The development of CO2 waveguide lasers with ceramic bodies has led to the wide availability of rugged, low to medium power CW sources at 10.6 μm. Utilising a new glaze bonding technique we have manufactured an alumina based, CO2 waveguide laser having a single, linear, 2.5 mm square bore and an overall length of 1 metre. With this straight forward approach to scaling up the active gain length, CW output power up to 58 watts has been demonstrated.
