Multi-color, multi-beam interferometry of laser-generated XUV harmonic radiation
We present a novel interferometric setup working in the XUV spectral range. The interferometer consists of a multi-pinhole mask and a transmission grating. In the case the light source consists of discrete spectral lines as is the case for laser-generated high harmonics the interferometer is capable of recording interferograms for multiple colors simultaneously. The device presented in this publication is an improvement of our recently published setup in a way which allows, in principle, for single-shot measurements of the temporal coherence length of a set of high harmonics. We present an experiment in which the influence of a spectral chirp of the driving laser on the coherence length of the generated harmonic radiation is studied.
