Optical seminar | 12 March 2021

The talk will present the basics of aqueous photonics. I will talk about the features of liquid plasma-based sources of broadband terahertz radiation [1, 2]. Nonlinear terahertz optics, its prospects and possible applications will be discussed separately. I will tell you why the use of liquid media allows achieving extremely high values of the nonlinear refractive index in the THz frequency range [3].
