Biaolong Liu

Biaolong Liu is a researcher at the Laboratory for Non-linear Optics within the Photon Science Division of the Paul Scherrer Institute. His work focuses on developing advanced laser sources for terahertz (THz) and mid-infrared applications, with a specific emphasis on coherent phase control in complex materials.

• Bachelor Degree in Condensed Matter Physics (2011) from University of Science and Technology of China (USTC)
• PhD under Prof. Andrea Cavalleri at the Max Planck Institute for the Structure and Dynamics of Matter (Hamburg)

His research spans nonlinear Mid-IR to THz light-wave generation and non-equilibrium spectroscopy on complex oxides, particularly high-Tc cuprates. He pioneered techniques for generating tunable narrowband THz pulses to explore transient superconducting correlations and optical strain engineering in antiferromagnetic materials.

Research Trends: His publications highlight expertise in terahertz photonics, ultrafast material dynamics, and nonlinear optical crystal applications. Key themes include frequency-tunable THz sources, non-equilibrium superconductivity, and phonon-driven magnetic polarization.

• Scientific Awards: Recognized as a 'highly-qualified young researcher' for leading high-power laser projects
