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.
Understanding the interaction between light and matter at the smallest scales (angstrom scale) is essential for advancing technology and materials science. Atomic-scale structures, such as defects in diamonds or molecules ...
