The first-order Raman band of diamond anvils has been investigated at pressure up to 410 GPa in order to develop an optical pressure determination method. The high-frequency edge of the band was calibrated by the pressure scale of the equation of state of Pt. A unique relationship between the edge-frequency and the sample pressure was confirmed up to the highest pressure, while the edge frequency reaches to 1907 cm−1 at 410 GPa. Usefulness of the diamond anvil Raman gauge as a laboratory-based pressure determination method in the multimegabar pressure range has been discussed.
