ABSTRACT:
A gas laser having preionization means which comprises an elongated glass tube extending beside the glow discharge volume for the length of the laser cavity, there being a central conductor inside the tube and a conductive strip or spaced strips bonded to the outside of the tube. The inner wire and outer strip are connected respectively to the same high voltage pulse leads which provide the main laser discharge. Ultraviolet radiation from the conductive strips on the tube preionizes the laser gas and creates a stable uniform laser electric discharge.
