MQ Safety Net: Unleashing anomalously-fast heat dissipation in diamond

Ultrafast heat dissipation has recently been detected in diamond lasers. This project aims to elucidate the underlying physics through the development of a novel optical-probe method for tracking the phonon heat-carriers in tandem with first-principles modeling. The knowledge will provide key insights into an extreme heat transport scenario of importance to lasers as well as potentially other extreme heat-handling systems. A key targeted outcome is the strengthening of national programs for next-generation high power lasers for applications in defence and space science. The project is well placed to benefit Australia by strengthening its technology and skill base in the areas of national security and high-tech manufacturing.
