An ultrahigh-pressure apparatus based on thermal energy is devised. In this apparatus, a sample inside the diamond anvil cell is irradiated with pulse YAG laser beam through diamond anvil. High pressure is generated by constraining thermal expansion of ultrahigh temperature region. The apparatus is equipped with a pressure measuring system based on the ruby fluorescence method. In order to examine the ultrahigh pressure ability of the apparatus, an aluminum particle put in 4:1 methanol/ethanol used as pressure medium was irradiated with a laser pulse.
