Pyrotechnically pumped laser uses the intense light of pyrotechnic chemical reaction as the pump light source. The mass and distribution of the powder influence the laser character directly. Variety of laser energy was observed when the unity of powder poles changed from 12 to 48. The two distributions of powders were compared. And then the rules of two elements’ influence on laser energy, i.e. the weight of chemical powder in reactions and the distribution of the chemical powder poles are given. Higher laser energy is achieved when 21 to 30 powder poles are used. The two distribution manners of same total poles were compared. The manner that poles concentrate to few wires is better than those to many wires. 1.003 J laser energy is achieved by use of 24 poles divided averagely to 3 series. The energy is 30 times the result obtained in earlier study, and the weight of chemical powder poles is only one fourth.
