High Energy Lab
In this laboratory, we produce our highest energy femtosecond pulses of 5 mJ (hence, "High Energy" lab) with a 1 kHz repetition rate from a Ti:Sapphire regenerative amplifier system. The high output power allows for a variety of nonlinear processes and generation of light from 240 nm to 20 µm as well as the Terahertz regime. The research in this lab utilizes Pump-Probe Spectroscopy in different domains of electromagnetic spectrum to study van der Waals materials [1-3], as well as interdisciplinary studies in neuroscience  and art conservation .
