我们报告了第一个实验演示的激光驱动的圆偏振软X射线激光链。它已经实现了通过播种32.8 nm的氪IX等离子体放大器与高次谐波光束，这已被圆偏振使用四反射器偏振器。我们的测量证明，放大辐射保持种子脉冲的初始偏振与我们的麦克斯韦-布洛赫模型很好地吻合。由此产生的全圆形软X射线激光束呈现高斯分布，每次发射产生约10（10）个光子，满足实验室规模光子需求应用实验的要求。
We report the first experimental demonstration of a laser-driven circularly polarized soft-x-ray laser chain. It has been achieved by seeding a 32.8 nm Kr IX plasma amplifier with a high-order harmonic beam, which has been circularly polarized using a four-reflector polarizer. Our measurements testify that the amplified radiation maintains the initial polarization of the seed pulse in good agreement with our Maxwell-Bloch modeling. The resulting fully circular soft-x-ray laser beam exhibits a Gaussian profile and yields about 10(10) photons per shot, fulfilling the requirements for laboratory-scale photon-demanding application experiments.
