Ultrafast spectroscopy is a method based on the exploitation of temporal dispersion for temporally stretching information encoded ultrashort optical pulses such that the information is detected and digitized by a slow photodetector and digitizer. Since it was conceived, it has enabled the observation of nonrepetitive and statistically rare events on ultrashort time scales. This workshop provides a forum for introducing the fundamental principles, emerging applications, and recent advances of ultrafast spectroscopy as well as for discussing its technical challenges and future perspectives.

Invited Speakers

Kotaro Hiramatsu, The University of Tokyo, Japan

Title: Large-scale single-cell analysis by ultra-rapid time-domain Raman spectroscopy

Abstract: Large-scale single-cell analysis by ultra-rapid time-domain Raman spectroscopy Abstract: We present a high-throughput (> 2,000 cells/s) vibrational flow cytometer which is realized by combining a rapid-scan Fourier-transform coherent anti-Stokes Raman scattering spectrometer with an acoustofluidic-focusing microfluidic device.
Cheng Lei, Wuhan University, China

Title: Time-stretch imaging and beyond

Abstract: We present the principle of optofluidic time-stretch microscopy and its application to precision medicine. Its ability to perform multiparametric image-based profiling of numerous single cells enables biomedical data mining with the help of machine learning.
Wang Lidai, City University of Hong Kong, China

Title: Ultrafast spectral-temporal photography from femtosecond to nanosecond

Abstract: TBD
Zhi-Chao Luo, South China Normal University, China

Title: Soliton transient dynamics in ultrafast fiber lasers

Abstract: We review our recent results on the investigations of soliton transient dynamics in ultrafast fiber lasers by real-time spectroscopy technique. Our findings may be useful for better understanding the soliton dynamics.
Dario Polli, Politecnico di Milano, Italy

Title: Broadband stimulated Raman scattering by a photonic time stretcher and other innovative detection schemes

Abstract: Coherent Raman scattering (CRS) microscopy enables non-destructive label-free chemical identification based on the intrinsic molecular vibrational spectrum. I will review broadband CRS and present recent results based on photonic time stretching and other innovative schemes.
Sascha Schäfer, The Carl von Ossietzky University of Oldenburg, Germany

Title: Ultrafast TEM: probing electron-light interactions at the nanoscale

Abstract: We report on our current developments on the optical control of free-electron beams in ultrafast transmission electron microscopy. Examples include the generation of attosecond electron pulse trains and the coupling of electrons to high-quality cavities.
Kevin K. M. Tsia, The University of Hong Kong, China

Title: Single-cell optofluidic and brain imaging

Abstract: We introduce our recently developed ultrafast optofluidic imaging techniques (multi-ATOM and FACED imaging) that allow deep biophysical/biochemical phenotypic profiles of millions of cells. Combined with high-throughput machine learning, their utilities in blood analysis and drug screen will be discussed.
Kenneth Kin-Yip Wong, The University of Hong Kong, China

Title: Ultrafast measurement by fiber parametric temporal imaging

Abstract: We present some recent advances in temporal imaging systems empowered by fiber parametric processes, particularly in the ultrafast applications on optical dynamics measurement for microresonator and fiber laser, and optical tomography at tens-of-MHz axial-scan rate.
