| Research Abstract |
Laser heating in diamond anvil cell (DAC) equipped with nano-polycrystalline diamond (NPD) anvils was tested for the first time using various types of lasers. NPD-based DAC was found to provide better heating efficiency than a standard DAC with single-crystal anvils. We observed high-temperature generation exceeding 5000 K and 3500 K during laser heating of hcp-Fe sample at pressures of ～100 and 170 GPa, respectively.
