Abstract
A description is given of CO2 laser heating system for attaining hightemperatures at pressure in a diamond-anvil cell (DAC). The mainpurpose of this paper is to demonstrate that a relatively inexpensiveset-up, perhaps affordable to many high-pressure laboratories, may becommissioned for laser-heated DAC experiments to achieve comparable extremeP–Tconditions to those attained with more sophisticated stations documented in theliterature. A novel idea of using the analogue output of a CCD camera to estimatethe peak temperature and map the temperature distribution across the hot-spothas been tested. In an additional initial experiment on cubic zirconia (c-ZrO2)we present evidence from a Raman characterization of the sample thattemperatures exceeding 4000 K have been obtained at pressure in the DAC.
