ABSTRACT:
A flow plate positioned upstream of the lasing cavity of an electrically pulsed gas laser blocks the transmission of shock waves generated in the laser cavity. The flow plate has a plurality of passages which are shaped to form a supersonic nozzle at the upstream end of the passage, a subsonic diffuser at the downstream end of the passage and a supersonic diffuser in the central region of the passage.
