Suppression of Small Scale Nonuniformity in the Line Focussing System Using Polarization Control and Regular Phase Distribution

Liu Zhongyong; Lu Baida; Cat Bangwei; Sui Zhan (Department of Opto-Electronic Science & Technology Sichuan University, Chengdu 610064)  
A method of suppressing interference speckle pattern on the plane of target produced from the segmented wedge array (SWA) line focussing system is investigated. The small scale nonuniformity caused by speckle is un favorable to producing X-ray laser.By using special distribution of polarizations and phases, speckles can be concentrated in more density, and the contrast of speckle can be reduced, which would be useful to smoothing speckles by thermal conduction within the target. In particular, for the fourelement SWA system, the speckles can be even entirely removed by using the method presented in this paper.
