Mission Impossible: THz Wave Loves Liquid Water

Speaker: Xi Cheng, Zhang (The Institute of Optics, University of Rochester)
Time: 10:00-12:00AM, Feb. 04, 2020
Location: Science Building 3, Room 353

Abstract: Three of states in ordinary 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 demonstrated that liquid water can generate broadband THz waves with the use of intense femtosecond laser pulses. I will report recent development of THz aqueous photonics, especially on the method of generation of coherent broadband THz wave from liquid water.
