Laser sources operating at the 1.2 μm wavelength band have some unique applications in photodynamic therapy, biomedical diagnosis and oxygen sensing. Additionally, they can be adopted as pump sources for mid-infrared optical parametric generation as well as visible light generation by frequency doubling.

Laser generation at 1.2 μm waveband has been achieved with different solid-state lasers including semiconductor lasers, diamond Raman lasers, and fiber lasers. Among these three types, the fiber laser thanks to its simple structure, good beam quality, and operation flexibility, is a great choice for 1.2 μm waveband laser generation.

Researchers led by Prof. Pu Zhou at National University of Defense Technology (NUDT), China, are interested in a high power fiber laser at 1.2 μm waveband. Current high power fiber lasers are mostly ytterbium-doped fiber lasers at 1 μm waveband, and the maximum output at 1.2 μm waveband is limited at 10-watt level.

Evolutionary biologists at Johns Hopkins Medicine report they have combined PET scans of modern pigeons along with studies of dinosaur fossils to help answer an enduring question in biology: How did the brains of birds evolve to enable them to fly?

The answer, they say, appears to be an adaptive increase in the size of the cerebellum in some fossil vertebrates. The cerebellum is a brain region responsible for movement and motor control.

The research findings are published in the Jan. 31 issue of the Proceedings of the Royal Society B.

XReal’s AR glasses aim to be an affordable alternative to Apple’s pricier Vision Pro, CEO Chi Xu told Bloomberg.

The findings aren’t as simple as increased detection, seen with increases in late-stage cancer for white women and mortality among Black women.

How can back-to-back atmospheric rivers impact the economy? This is what a recent study published in Science Advances hopes to address as a team of researchers led by Stanford University investigates the economic toll of back-to-back atmospheric rivers compared to single events. This study holds the potential to help scientists, the public, and city planners better prepare for atmospheric rivers, as they can cause widespread flooding in short periods of time.

For the study, the researchers analyzed data from the Modern-Era Retrospective Analysis for Research and Applications, version 2, (MERRA-2) between 1981 and 2021 and computer algorithms to ascertain the economic impact of atmospheric rivers throughout California. The goal was to ascertain how much worse back-to-back atmospheric rivers were compared to single events. The study’s findings discovered that back-to-back atmospheric rivers caused three times greater economic damage than single events, which is also higher when the first atmospheric river exhibits greater strength.

“Our work really shows that we need to consider the likelihood for multiple, back-to-back events for predicting damages, because damage from multiple events could be far worse than from one event alone,” said Dr. Katy Serafin, who is a coastal scientists and assistant professor in the Department of Geography at the University of Florida and a co-author on the study.
