A two-dimensional optical spectrometer is demonstrated using simple optical components. This spectrometer is based on ultrafast two-dimensional (2D) frequency-dispersed pump–probe spectroscopy and can be used for single-shot correlation spectroscopy. To demonstrate functionality of this device, we measure the 2D correlation spectrum of atomic rubidium.
