This paper investigates, theoretically and experimentally, the elements which influence the gain distribution of laser medium. A high gain laser module and a high energy storage laser module have been manufactured. The experiment results approved that the high gain laser module was pumped uniformly and a TEM00 output energy of 11.8mJ was achieved at a light-light efficiency of 15％. In the high energy storage laser module, a 6mm diameter Nd:YAG rod which is 100mm long was pumped by nine-diode arrays (the peak pump-power is 6 500kW) . Numerical calculation was done to optimize the distance between diode and Nd:YAG. The experiment result approved that the gain coefficient of this module is 0.3/cm, and the storage power is 400mJ per pulse．
