The soot produced by unburnt hydrocarbon flames is the second largest contributor to global warming, while also harming human health. Researchers have developed state-of-the-art, high-speed imaging ...

Femtosecond laser pulses, with durations on the order of 10⁻¹⁵ seconds, have transformed the landscape of ultrafast optics by enabling the exploration of rapid light–matter interactions. The dynamics ...

Ultrafast laser-material interactions are pivotal for advanced manufacturing, yet existing techniques often fail to capture comprehensive structural and optical changes simultaneously. In a new paper ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how ...

LS-CUP for time-resolved 2D imaging of laser-induced flame signals. (a) Photograph of the studied flame. The regions of investigation at heights h1 and h2 are labeled. (b) Illustrations of four ...
