In the CLEAR lab we endeavor to understand large scale geological processes that operate deep inside planets. Our approach is to recreate high pressure-temperature conditions and examine various physical properties of minerals and rocks (in situ) using state-of-the-art spectroscopic techniques. Specifically, we use statically- and dynamically-heated diamond anvil cells together with a pulsed time-resolved broadband optical probes (e.g. absorption, reflection, fluorescence, Raman) and a precisely-synchronized detector to explore the properties of planetary mantles and technological materials at extreme conditions. Details on the experimental setup and its capabilities are provided here.
