Abstract

ABSTRACT: VIPA-based Brillouin spectroscopy is implemented for in-situ measurements at high pressure and temperature in laser-heated diamond anvil cells. Its performances are compared to those of the widely used Tandem Fabry–Perot instrument. A significant reduction of the collection time is in particular enabled. The usefulness of VIPA-Brillouin spectroscopy for High Pressure studies is here illustrated by revisiting the nitrogen melting curve up to 45 GPa. VIPA-Brillouin spectroscopy has the potential to become an important platform to investigate the equation of state properties of warm dense molecular systems.
