In this paper we report on the results of comparative investigations of different pump cavities. Numerical estimations of the geometrical transfer efficiency of various cavities are presented. An experimental study of the pumping efficiency and pumping uniformity of the laser heads with respect to the cavity geometry, types of flashlamp, and reflecting coatings have been carried out. The influence of the discharge circuit on the pumping efficiency is also discussed.
