We introduce a spectrometer capable of measuring sample absorption spectra in the visible regime, based on a time-domain scanning Fourier transform (FT) approach. While infrared FT spectrometers typically employ a Michelson interferometer to create the two delayed light replicas, the proposed apparatus exploits a compact common-mode passive interferometer that relies on the use of birefringent wedges. This ensures excellent path-length stability (∼λ/300) and accuracy, with no need for active feedback or beam tracking. We demonstrate the robustness of the technique measuring the transmission spectrum of a colored bandpass filter over one octave of bandwidth and compare the results with those obtained with a commercial spectrophotometer.read more

Spatially resolved Fourier transform spectroscopy in the extreme ultraviolet
TL;DR: In this article, an ultrastable common-path interferometer was proposed for high-intensity laser pulses that drive the table-top high-harmonic generation (HHG) process, which enables the generation of fully coherent XUV pulse pairs with sub-attosecond timing variation, tunable time delay, and a clean Gaussian spatial mode profile.
