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.
A small yet innovative experiment is taking place at CERN. Its goal is to test how the CERN-born optical timing signal—normally used in the Laboratory's accelerators to synchronize devices with ultra-high precision—can ...
