This paper investigates, theoretically and experimentally, the elements which influence the gain distribute of laser medium. A high power storage laser module has been manufactured. In this module a 6 mm diameter Nd:YAG rod which is 100 mm long is pumped by nine diode-arrays (the peak pump-power is 6500 W). Each array consisted of nine diodes. On account of the uniformity of distribute in whole laser medium, a Nd-doping of 0.6% laser rod is chosen, and in order to eliminate self-oscillation, two ends are made to inclined planes. Numerical calculation has been done to optimize the distance between the diode and Nd:YAG. The experiment result approved that the gain coefficient of this module is 0.3 cm-1, from it we can infer that the storage power is about 400 mJ per pulse.
