以下のとおりセミナーを開催されました。
日時：２０２５年１０月９日（木）13:00～14:30
場所：東京大学理学部1号館340号室
講演者： Herve Rigneault 氏 (Full Professsor and CNRS research Director,
Institut Fresnel, Aix-Marseille University)
講演題目： Coherent Raman imaging in the time and frequency domains
In this seminar, I will present coherent Raman techniques in both the time and frequency domains.
Time-domain coherent Raman can probe low vibrational frequencies using a short excitation pulse
that drives the molecular vibration, followed by a time-delayed probe pulse that measures the transient vibrational refractive index through frequency shifts. Using an ultrafast acousto-optic delay line, I will demonstrate that low-frequency hyperspectral Raman imaging is possible at 6 frames per second over a 200 μm field of view. I will also present recent results obtained with temporally shaped pump and probe pulses, which can be used to selectively enhance or suppress vibrational excitations.
In the second part of the seminar, I will discuss our recent advances in frequency-domain coherent Raman for chemical imaging of high vibrational frequencies. I will show how narrowband coherent Raman can be used to perform histology with a quality comparable to classical paraffin-embedded
histology performed in hospitals. I will also present our recent work on implementing nonlinear imaging in flexible endoscopes using novel hollow-core fibers.
