Enhanced interferometric detection in two-dimensional spectroscopy with a Sagnac interferometer.
An intrinsically phase-stable Sagnac interferometer is introduced for optimized interferometric detection in partially collinear two-dimensional (2D) spectroscopy. With a pump-pulse pair from an actively stabilized Mach-Zehnder interferometer, the Sagnac scheme is demonstrated in broadband, short-wave IR (1-2 μm), 2D electronic spectroscopy of IR-26 dye.
