摘要:
Matter has four states: solid, liquid, gas, and plasma. The generation of THz wave from solids, gases, and plasmas has been well understood for decades. However, the demonstration of THz wave generation from liquid sources was conspicuously absent, especially from liquid water due to water’s infamously strong absorption characteristics in the THz regime. It is reasonable to expect that liquids might have unique properties if they could be harnessed as THz sources. Liquids have a high density, close to that of solids, meaning that light over a certain area will interact with many more molecules than an equivalent cross-section of gases. This makes liquids very good candidates for the study of high-energy-density plasma. A successful investigation in THz generation from liquid water will complete the last piece of the matter-phase puzzle for THz sources.

简介：
Professor Xi-Cheng Zhang's research interests center around Terahertz waves, also known as T-rays, which exist within a frequency range between microwave and infrared. His research is focused on the generation, detection, and applications of free-space THz beams with ultrafast optics.
Professor Xi-Cheng Zhang is M. Parker Givens Professor at The Institute of Optics, University of Rochester. A Fellow of AAAS,APS, IEEE, OSA, and SPIE, his recent awards include 2017 Albert Nelson Marquis Lifetime Achievement Award; 2017 Australian Academy of Science Selby Fellowship; 2014 International Society of IRMMW-THz Button Prize; 2012 OSA William F.Meggers Award; 2011 IEEE Photonics Society William Streifer Scientific Achievement Award; and 2009 Rensselaer William H.Wiley Award. He holds 14 professorships in foreign countries,29 US patents, has authored or co-authored over 400 refereed scientific papers. Professor Zhang is the Editor-in-Chief of Optics Letters.
