Experiments at high temperature and pressure - Laser heating through the diamond cellCW laser heating through a diamond anvil cell by means of a focused Nd:YAG laser has resulted in the achievement of temperatures in the 1500-5000 K range for pressures of 10-100 GPa. Temperatures are determined radiometrically, with an accuracy of about 200 K, and temperature variation across the laser-heated spot is derived by means of spatial filtering with a slit that can be scanned. Melting temperatures are thus determined either on the basis of observed temperature at the liquid-solid interface or on that of the peak temperature at which glass is first produced with increasing laser power.
