Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of scientific and industrial applications. From creating stupendously accurate clocks to processing the petabytes ...
Scientists at Japan's Institute for Molecular Science have achieved a 1,000-fold enhancement in white-light generation inside water by using non-harmonic two-color femtosecond laser excitation. This previously unexplored ...
Last week, four lasers were projected into the sky above the European Southern Observatory (ESO) Paranal site in Chile. The lasers successfully created an "artificial star" that astronomers can use to measure and then correct ...
Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and research. The problem: efficient short-pulse lasers require a lot of space and are expensive.
Physicists at Umeå University, in collaboration with researchers in China, have developed a laser made entirely from biomaterials—birch leaves and peanut kernels. The environmentally friendly laser could become an inexpensive ...
Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than previously possible. This advance ...
Forests have been benefiting humanity since long before the health benefits of forest bathing were discovered. They are major carbon sinks that provide a wide range of ecosystem services, including timber and non-timber forest ...
A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study, published in Physical Review Letters, shows ...
According to a recent study published in APL Photonics, a research team led by Prof. Liang Xu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed an ultra-compact excimer laser roughly ...
Researchers at Umeå University and the Swedish Defense Research Agency, FOI, have developed new laser methods that can quickly detect chemical weapons and harmful bacteria directly on site—without the need to send samples ...
