heal.abstract	The influence of the applied voltage pulse polarity on the performance of a HF laser pumped by a sliding surface discharge is investigated. Details are presented for the polarity dependense of the discharge properties as well as for their relation to the physical processes that affect the sliding discharge evolution. The output energy and efficiency were higher when the initiating or stressed electrode was in relative positive potential, irrespective of which electrode was grounded. The experimental results indicate that for positive polarity the discharge was more uniform, self terminating in type, with reduced electron density and temperature. The increase in output energy and efficiency is attributed to the improvement of the spatial uniformity of laser pumping, to a more efficient utilization of discharge input energy due to an increase in the steady state discharge time phase, as wett as to the reduced electron temperature and to the increased steady state voltage which may also result in more efficient laser pumping.	en
