<p>A bifilar helical electrode arrangement for the transverse excitation of gaseous laser media and particularly adapted to produce laser radiation in those gaseous laser media, such as nitrogen, which are characterized by an extremely short lifetime of the upper laser level As a consequence of the electrode geometry, the invention favours the generation of laser beams exhibiting a circular symmetric beam cross section which can easily be focused using customary spherical optics. The invention incorporates intertwined helical anode and helical cathode structures together with capacitors that are connected to the helical electrode structure via low-resistance and low-inductance leads or are directly interposed between successive convolutions of that helical electrode structures.</p> |
