种子单通自由电子激光器是有前途的相干、短持续时间和强光源，从可见光到x射线。操作可调的波动器，他们也是一个独特的装置，提供完全可变的极化辐射。本文首次报道了可变极化源的螺旋波动子的播散。我们证明了种子偏振和聚焦的调整可以使自由电子激光辐射在强度和质量上得到优化。
Seeded single pass free-electron lasers are promising coherent, short-duration, and intense light sources, from the visible to x rays. Operated with adjustable undulators, they are also a unique device for providing fully variable polarized radiation. We report here the first seeding of helical undulators with a variable polarized source. We demonstrate that the adjustment of the seed polarization and focusing allows the free-electron laser radiation to be optimized in terms of intensity and quality.
