HIGH POWER GAS LASER

摘要

HIGH POWER GAS LASER A region is provided for maintaining a glow discharge in a flowing laser gas mixture. The gas laser apparatus includes an arc plasma source for providing a plasma gas stream which is rich in electrons and/or metastables. The plasma gas is other than the laser gas, and the plasma stream assists the glow discharge such that a non-arcing glow discharge can be established in the glow discharge region.
