Raman scattering system for a laser heated diamond anvil cell

A Raman scattering system has been developed for in situ measurements under high pressure and high temperature (HPHT). This system integrates micro-Raman spectroscopy equipment with a double-sided laser heating system for a diamond anvil cell. The laser heating system allows one to generate P-T conditions over one megabar and thousands of degree Kelvin. In this article, in situ HPHT Raman measurements have been carried out on NaBi(WO4)(2) to 1.2.2 GPa and 1658 K. (C) 2004 American Institute of Physics.
