Electronics Research provides insight into ultrafast laser pulse behaviour News Andrew Czyzewski 20 Dec 2011 Insights into the behaviour of ultrafast laser pulses could improve their performance in manufacturing, diagnostics and research. This series of high-speed images shows how plasma expands when material is exposed to ultrafast laser pulses. Purdue researchers have discovered details that could help to harness the technology for applications in manufacturing, diagnostics and research.
