ABSTRACT:
Laser apparatus including a relatively long cylindrical cathode within a discharge tube containing a buffer gas at a low pressure of less than 1 Torr. By employing a laser constructed according to the invention, it is possible to achieve a plasma which extends along the length of the cathode, which may be up to one meter long.
