Sen Mou

I obtained my Ph.D. in 2018 at the University of Naples Federico II. My research interests focus on ultrafast optics, THz photonics, vortex beams, hybrid organic-metal perovskite materials, 2D materials, etc. I have extensive experience in regenerative chirp-pulse-amplification laser systems, optical parametric amplifiers, and optical parametric chirped-pulse amplification laser systems. I built setups for THz generation with laser-induced plasma and optical rectification in nonlinear crystals, optical-pump THz-probe, z-scan, etc. I currently work on THz imaging. I have 27 journal articles, 1 conference article, 3 patents, and more than 250 citations. I am the recipient of INFN postdoctoral fellowship.
