Pulsed digital holography, which combines femtosecond pulsed laser and digital holography, is a novel technology for detecting ultrafast transient processes in real-time. Pulsed digital holography can obtain a series of amplitude and phase information of the ultrafast process in one shot at the femtosecond or picosecond order, and comprehensively characterize the whole picture of the ultrafast process. However, the system of pulsed digital holography currently has the defects of complexing, poor stability, small number of pulse frames, and low utilization of space bandwidth, which seriously limits practical applications. In this work, a real-time detection system is designed for ultrafast transient processes, which has the property of high stability, femtosecond or picosecond time order resolution, and adjustable pulse frames. The pulsed lasers are used instead of traditional continuous lasers. The proposed system design provides a competitive approach to ultrafast transient imaging.

In this paper, we propose an approach for implementing quantum-enhanced stimulated Raman scattering (QESRS) microscopy using a dual-polarization scheme. This approach has advantages for high-power operation and enables ultrasensitive Raman detection of molecular vibrational mode symmetry. To demonstrate the feasibility and effectiveness of our technique, we present both the theoretical framework and experimental results of dual-polarization QESRS. Our technique resulted in a noticeable reduction of noise on both parallel and orthogonal QESRS spectra as well as on the depolarization ratio spectra. These results validate the potential of our approach for achieving high-speed QESRS imaging with sub-shot-noise sensitivity.
