Abstract
Industrial CO2 laser in range of sub-kilowatt and kilowatt has progressed from large, heavy slow axial flow laser excited by DC longitudinal discharge to compactness, efficient fast axial flow (FAF) laser excited by DC longitudinal or transverse RF discharge. However, it is very difficult to get stable discharge because of flow disturbance causing by high gas pressure and flow velocity. Based on experiment, we have designed a FAF CO2 laser excited by DC longitudinal discharge with 4 segments of plasma tubes in series to get current-stabilized and 'non- pinch" discharge in plasma bore, CW 600W of power output can be obtained along 0. 94m of total gain length with power stability of less than ± 1. 5%.
