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.
Using ultra-fast laser beams, a team from the Irradiated Solids Laboratory has designed an experiment that allows both the creation of nanometric cavities in metal films and their study using several advanced microscopy techniques. ...
