Abstract

We demonstrate the generation of a coherent x ray in the water window region in a gas cell filled with neon gas using a wavelength-tunable mid-IR femtosecond laser operating at 1 kHz repetition rate. The cutoff energy and conversion efficiency of the water window x ray can be optimized by tuning gas pressure as well as the focal position.

摘要

我们展示了在一个充满氖气的气室中，利用重复频率为1 kHz的波长可调谐中红外飞秒激光，在水窗区域产生相干X射线。通过调节气体压力以及焦点位置，可以优化水窗X射线的截止能量和转换效率。
