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 ...

Researchers at Michigan State University (MSU) have developed a novel method to control the location and timing of crystal growth precisely. This could help many advanced technologies, such as solar ...

Darwin Quiroz is exploring new frontiers in miniature lasers with major biomedical applications. When Quiroz first started working with optics as an undergraduate, he was developing atomic ...

Nobel laureate Arthur Schawlow’s advice to “never measure anything but frequency” is a central principle of modern precision metrology and timekeeping. Today’s spectroscopy is advanced enough to teach ...
