ABSTRACT:
A pair of elongated, parallel electrodes (91,92) are insulatively mounted within a tubular housing (111) filled with a laser gas mixture between an arrangement of reflective optical elements (120,150) sealingly mounted at each end of the housing. The electrodes form a rectangular gas discharge area (40) the minimum spacing (A) between which is the diameter of the fundamental free-space mode of the stable, laser resonator (17) formed in the gap when the electrodes are rf excited (13). A multi-pass optical configuration (30,50) uses the full width (B) of the active medium to produce a high power, compact laser (10,200). Deformable support rings (97) are compressed to push the electrodes apart against small cylindrical spacers (99) abutting the inner walls of the housing to maintain the electrodes' spatial relationship. The rf feeds (103) sealingly (112) connected to the electrodes through the housing without disturbing the uniform distribution of forces on the electrodes. Air cooled heatsinks (161,162, 176,177) are held tightly against while being flexibly mounted to the laser tube assembly reducing mechanical and operational torsional distortion, misalignment and instability.
