摘要

我们介绍了一种结构紧凑、内在稳定的共路径干涉仪，用于自由电子激光器（FEL）的播种。该干涉仪可处理所需的紫外线种子波长，在 265 纳米波长处具有 10 mrad 的出色相位稳定性。通过为 FEL FERMI 提供种子波长，我们展示了在 52.5 纳米波长下产生的具有可调延迟和 6 倍延迟稳定性的极紫外（XUV）脉冲对。其应用前景包括傅立叶变换光谱学、非线性光谱学以及 XUV 和 X 射线领域的相干控制实验。

Generation of interferometrically stable pulse pairs from a free-electron laser using a birefringent interferometer

We present a compact, intrinsically stable common path interferometer for the seeding of free-electron lasers (FELs). The interferometer can handle the required ultraviolet seed wavelengths and features an excellent phase stability of 10 mrad at 265 nm. By seeding the FEL FERMI, we demonstrate the generation of extreme ultraviolet (XUV) pulse pairs with tunable delay and a delay stability of 6 as at 52.5 nm. Prospective applications are Fourier transform spectroscopy, nonlinear spectroscopy and coherent control experiments in the XUV and x-ray domain.

期刊介绍： Published twice-monthly (24 issues per year), Journal of Physics B: Atomic, Molecular and Optical Physics covers the study of atoms, ions, molecules and clusters, and their structure and interactions with particles, photons or fields. The journal also publishes articles dealing with those aspects of spectroscopy, quantum optics and non-linear optics, laser physics, astrophysics, plasma physics, chemical physics, optical cooling and trapping and other investigations where the objects of study are the elementary atomic, ionic or molecular properties of processes.
