As the laser pumping source, pulsed xenon flash lamp is widely used in high power laser amplifier system such as inertial confinement fusion projects. The radiation efficiency of pulsed xenon flash lamp is the crucial parameter. In our previous work, it has been proven that the pulsed xenon flash lamp with annular section has higher radiation efficiency as well as laser amplifier efficiency compared with traditional flash lamp. To further improve the characteristics of this kind annular section flash lamp, a multi-electrode system was proposed for annular section flash lamp in this paper. Experimental results shown that the discharge channels established more quickly and expended fast to whole lamp tube space. Also the distribution of the discharge plasma is more uniform. The novel multi-electrode xenon flash lamp has been investigated in the aspects of the electrical characteristics, the discharge plasma channel, radiation and neodymium doped glass fluorescence. Experimental results show that discharge and radiation characteristics of xenon flash lamp with multi-electrode structure are improved. The detail mechanisms of the improvements for the multi-electrode structure will be discussed in this paper.
