New pre-print: A solid-state high harmonic generation spectrometer with cryogenic cooling
Sep 7 2023

Solid-state high harmonic generation spectroscopy (sHHG) has emerged as a pivotal technique for delving into electronic structure, symmetry, and dynamics in condensed matter systems. In our latest manuscript, we introduce an advanced cryogenic sHHG spectrometer, uniquely designed with a vacuum chamber and a closed-cycle helium cryostat. With the aid of an in situ temperature probe, we’ve ascertained that the sample interaction region maintains cryogenic temperatures even during the application of high-intensity femtosecond laser pulses, which are responsible for generating high harmonics. Our approach paves the way for temperature-dependent sHHG measurements down to a few Kelvin. Such advancements in sHHG spectroscopy present a novel tool for investigating phases of matter that manifest at low temperatures, an area of particular intrigue for highly correlated materials.

Our group welcomes Prof. Dean Smith from the University of Nevada, Las Vegas. Dean is a frequent collaborator of our group on applications of high pressure science probed with nonlinear spectroscopies and will be visiting our group for the next year.

Michael receives DOE Early Career Award
Aug 4 2023

We are excited to share that Michael was among this year’s awardees of the prestigious DOE Early Career Research Program Award. In this 5-year award on the topic “Ultrafast mechanisms of chirality control in electronic materials” we will use new capabilities of our attosecond instrument in combination with facilities at SLAC to study control mechanisms of chiral order in quantum materials.
