“…Pump-probe spectroscopy is a standard tool in nonlinear optics for characterization of light induced changes in optical properties of materials, and for studying the relaxation dynamics of excited states [2]. We chose methylene blue as a demonstration contrast agent for PPOCT because it has spectrally distinct ground-state absorption in the visible region and triplet-triplet absorption in the 830 nm region, which is commonly used for OCT [3].…”

“…Optical heterodyne detection (OHD) is a linear interferential method in which the weak signal is mixed with, and amplified by, a strong Local Oscillator (LO) field. The phase locked LO acts as an amplifier and as a phase reference that enable the separate measurement of the spectral amplitude and phase of the probe spectral components [14,15,16,17,18,19,20]. The signal to noise ratio of OHD can be improved by means of balanced detection [21].…”

Unveiling and controlling the coherent evolution of low energy states is a key to attain light driven new functionalities of materials. Here we investigate the coherent evolution of non-equilibrium photon-phonon Raman interactions in the low photon number regime via femtosecond time-resolved multimode heterodyne detection. The time dependence of the weak probe spectral components is revealed by interferential amplification with shaped phase-locked reference fields that allow for a frequency selective amplification. We report measurements on α-quartz that show that both amplitude and phase of the probe spectral components are modulated at the phonon frequency, but encode qualitatively different responses which are representative respectively of the time dependent position and momentum of the atoms. We stress that the sensitivity achieved here (1-10 photons per pulse) may be of relevance for both quantum information technologies and time domain studies on photosensitive materials.

“…In OHD, a weak signal is amplified by the interference with a strong local oscillator (LO). The phase-locked LO acts as an amplifier and enables the direct measurement of the amplitude and phase of the signal with improved sensitivity and high signal-to-noise ratio [16][17][18][19][20][21][22][23][24][25].…”

Unveiling and controlling the time evolution of the momentum and position of low energy excitations such as phonons, magnons, and electronic excitation is the key to attain coherently driven new functionalities of materials. Here we report the implementation of femtosecond time-and frequencyresolved multimode heterodyne detection and show that it allows for independent measurement of the time evolution of the position and momentum of the atoms in coherent vibrational states in α-quartz. The time dependence of the probe field quadratures reveals that their amplitude is maximally changed when the atoms have maximum momentum, while their phase encodes a different information and evolves proportionally to the instantaneous atomic positon. We stress that this methodology, providing the mean to map both momentum and position in one optical observable, may be of relevance for both quantum information technologies and time-domain studies on complex materials.
