摘要

基于VIPA的布里渊光谱用于激光加热金刚石砧座电池中高压和高温下的原位测量。它的性能与广泛使用的串联法布里-珀罗仪器进行了比较。特别是可以显著缩短收集时间。VIPA布里渊光谱在高压研究中的有用性在这里通过重新查看高达45的氮熔融曲线来说明 GPa。VIPA布里渊光谱有可能成为研究热稠密分子系统状态方程性质的重要平台。

Performances of a VIPA-based spectrometer for Brillouin scattering experiments in the diamond anvil cell under laser heating
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.
