报告简介：

Three of four states in matter: solid, gas, and plasma have been all used for THz wave generation for decades. However, until recently, the demonstration of THz wave generation from liquid sources was conspicuously absent. It is well known that water is a strong absorber in the THz frequency range, therefore liquid water has historically been sworn off as a source for THz radiation. Once thought impossible, we have experimentally demonstrated that liquid water can generate intense and broadband THz waves with the use of femtosecond laser pulses. I will report recent development of terahertz aqueous photonics, especially the generation of coherent THz wave from liquid water.

Xi-Cheng Zhang – Parker Givens Chair of Optics, was Director of The Institute of Optics, University of Rochester, NY, a foremost institution in optics and optical physics research and education (Jan. 2012 –June 2017). Prior to joining UR, he pioneered world-leading research in the field of ultrafast laser-based terahertz technology and optical physics at Rensselaer Polytechnic Institute, Troy NY (‘92-‘12). At RPI, he is the Eric Jonsson Professor of Science; Acting Head at the Department of Physics, Applied Physics & Astronomy; Professor of Electrical, Computer & System; and Founding Director of the Center for THz Research. He is co-founder of Zomega Terahertz Corp. With a BS (‘82) from Peking University,he earned the MS (‘83) and PhD degree (‘86) in Physics from Brown University, RI.

Dr. Zhang served as Editor-in-Chief of Optics Letters, OSA (‘14-‘19). Previous positions included visiting scientist at MIT (‘85), Physical Tech. Division of Amoco Research Center (‘87), EE Dept. at Columbia University (‘87–‘91); Distinguished Visiting Scientist at Jet Propulsion Lab, Caltech (2006). He holds 29 US patents, and is a prolific author and speaker.

His honors and awards include: Humboldt Prize (’18); Australian Academy of Science Selby Fellow (’17); IRMMW-THz Kenneth Button Prize (‘14); OSA William F. Meggers Award (‘12); IEEE Photonics Society William Streifer Scientific Achievement Award (‘11); Rensselaer William H. Wiley 1866 Award (‘09);Japan Society for the Promotion of Science Fellowship & NRC-CIAR Distinguished Visiting Scientist, Canada (‘04); First Heinrich Rudolf Hertz Lecturer, RWTH, Aachen, Germany (‘03). He also served two years as a Distinguished Lecturer of IEEE/LEOS. He received Rensselaer Early Career Award (‘96), Research Corporation Cottrell Scholar Award (‘95), NSF Early Career Award (‘95), K.C. Wong Prize, K.C. Wong Foundation, Hong Kong (‘95), NSF Research Initiation Award (‘92). In ‘93-‘94, he was an AFOSR-SRPF Fellow at Hanscom Air Force Base.
