ABSTRACT:
A high frequency, high energy RF powered laser is shown and described. This laser utilizes a stripline wave guide electrode, a ground plane, and dielectric materials for the lasing tube to provide for resistance to spurious discharge and parasitic breakdown between the stripline and the ground plane. The use of a high voltage pulse to initiate lasing gas breakdown, the use of a dielectric section in the stripline wave guide to protect the RF source and a choke to protect the high voltage pulse source from RF energy are also shown and described.
