Optics & lasers as a research area encompasses the fundamental and applied study of the generation, propagation, manipulation, and detection of light, with a particular emphasis on coherent and monochromatic radiation from lasers. It includes laser physics (gain media, optical cavities, nonlinear and quantum optical effects), beam shaping and guiding (waveguides, fibers, integrated photonics), optical materials and devices (mirrors, modulators, detectors), and advanced techniques such as ultrafast optics, high-power and high-intensity laser systems, laser spectroscopy, and laser-based metrology. This field underpins technologies in precision measurement, optical communication, imaging, microfabrication, and control of matter with light.
For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating from the Crab Pulsar, the remnant of a supernova observed by Chinese and Japanese astronomers in the ...
