How can lasers and resistance heaters expand the conditions reached in diamond-anvil cells?

In the context of high-pressure physics, the use of resistance heaters and lasers has significantly expanded the capabilities of diamond-anvil cells. By integrating these heating methods, researchers can subject samples to a broader range of pressure-temperature conditions, effectively replicating the extreme environments that prevail within most of the solid Earth.1

While the diamond-anvil cell is primarily recognized for its ability to sustain record-breaking high pressures, the addition of these heating techniques allows for the study of materials under combined conditions of intense heat and compression that were previously inaccessible.1
