• We report a novel CO2 laser electrode prepared using an arc thermal spray process. A pair of helical aluminum (Al) layers sprayed on the wall of a quartz laser tube served as electrodes for AC discharge. The quality of an electrode is affected by the Al wire purity and porosity/oxide content of the coating. Al2O3 grit size affected the surface roughness of the quartz tube and the bonding strength between the quartz and Al coating. We coupled AC power into sprayed laser electrodes using a parallel resonant inverter to obtain 500W output power from a fast-axial-flow (FAF) CO2 laser. The thermal spraying of electrodes is attractive due to its ease of preparation, high reliability, and low cost.
