“…39 TWINS uses birefringence to impose an arbitrary delay on two orthogonal polarization components by continuously varying the material thickness. TWINS has already been successfully implemented in the visible 39 and the IR 40 ranges demonstrating excellent phase stability and reproducibility. In this paper, we describe in detail our 2DES setup, working in the partially collinear pump-probe geometry and using TWINS to generate the phase-locked pump pulses.…”

“…This is corrected by the static block C, consisting of two wedges identical to those in block B, and placed as close as possible to block B (typically less than 5 mm) to minimize the lateral displacement between the pump pulses, which is negligible under our experimental conditions. 40 The insertion of the wedges of block C into the beam can be kept small and is also used to finely tune the dispersion introduced by the overall sequence (see Sec. III C).…”

We present a simple experimental setup for performing two-dimensional (2D) electronic spectroscopy in the partially collinear pump-probe geometry. The setup uses a sequence of birefringent wedges to create and delay a pair of phase-locked, collinear pump pulses, with extremely high phase stability and reproducibility. Continuous delay scanning is possible without any active stabilization or position tracking, and allows to record rapidly and easily 2D spectra. The setup works over a broad spectral range from the ultraviolet to the near-IR, it is compatible with few-optical-cycle pulses and can be easily reconfigured to two-colour operation. A simple method for scattering suppression is also introduced. As a proof of principle, we present degenerate and two-color 2D spectra of the light-harvesting complex 1 of purple bacteria.

“…[33,[137][138][139] Neue Verfahren für die Detektion und Datenerfassung werden entwickelt um die Datenqualität zu verbessern und um Zugang zu neuen Observablen zu erhalten. [25,87,[140][141][142][143][144] 2D-IR-Spektren zeigen viele Details der molekularen Welt, dementsprechend müssen die theoretischen Methoden, die die Interpretation der Spektren stützen, sehr leistungsfähig sein. Dies gilt umso mehr für die hier diskutierten 2D-Spektroskopien, die auch elektronisch angeregte Zustände und starke Abweichungen vom Gleichgewicht beinhalten.…”

Ultraschnelle, mehrdimensionale Infrarot‐Spektroskopie ist eine leistungsstarke Methode, um Informationen über molekulare Strukturen und deren Dynamik zu erhalten, die mit linearer Spektroskopie nicht oder nur schwer zugänglich sind. IR‐Pulssequenzen mit resonanten oder nichtresonanten UV‐, Vis‐ oder NIR‐Pulsen erweitern den Einsatzbereich der mehrdimensionalen Schwingungsspektroskopie erheblich und schaffen Möglichkeiten, die weit über die eines reinen IR‐Experimentes hinausgehen. Dazu gehört die oberflächenspezifische 2D‐IR‐Spektroskopie, deren Empfindlichkeit die Untersuchung molekularer Monolagen ermöglicht, die ultraschnelle Strukturbestimmung in Nichtgleichgewichtssystemen, die getriggerte Austauschspektroskopie, die es erlaubt, Edukt‐ und Produktbanden miteinander zu korrelieren, Untersuchung des Zusammenspiels von elektronischen und Kernfreiheitsgraden, die Untersuchung von Wechselwirkungen zwischen Raman‐ und IR‐aktiven Moden, Bildgebung mit chemischem Kontrast, subensembleselektive Photochemie und sogar das Steuern von Photoreaktionen durch selektive IR‐Anregung. Im Folgenden stellen wir nützliche gemischte IR/nicht‐IR‐Pulssequenzen vor, diskutieren deren Eigenheiten und veranschaulichen ihr Anwendungspotenzial.

“…As the two fields share a common optical path, their phase delay can be adjusted with interferometric precision and displays an exceptionally high long-term stability, with phase jitter smaller than 1/360th of the optical cycle over 30 minutes, without active stabilization or tracking. 25 The TWINS interferometer has been successfully employed as a FT spectrometer in spectral ranges from the visible 27,28 to the mid-infrared 29,30 , with both coherent and incoherent light beams. This approach combines the advantages of FT spectroscopy with the robustness and accuracy of a common-path interferometer.…”

We introduce a wide field hyperspectral microscope using the Fourier-transform approach. The interferometer is based on the Translating-Wedge-Based Identical Pulses eNcoding System (TWINS) [Opt. Lett. 37, 3027 (2012)], a common-path birefringent interferometer which combines compactness, intrinsic interferometric delay precision, long-term stability and insensitivity to vibrations. We describe three different implementations of our system: two prototypes designed to test different optical schemes and an add-on for a commercial microscope. We show high-quality spectral microscopy of the fluorescence from stained cells and powders of inorganic pigments, demonstrating that the device is suited to biology and materials science. We demonstrate the acquisition of a 1Mpixel hyperspectral image in 75 seconds in the spectral range from 400 to 1100 nm. We also introduce an acquisition method which synthesizes a tunable spectral filter, providing band-passed images by the measurement of only two maps.
