Advances in Lasers and Optical Amplifiers: Materials, Components, and Systems

During the last decades a lot of research activities in the field of photonics have been accomplished and today there is a disruptive revolution underway where the photons are used to transmit, store, and process information. Laser and optical amplifier technology plays an important role in these events. In particular, the advances in lasers and optical amplifiers, enabling novel, powerful and exciting applications are based on research results arising from different investigation fields. This special issue is an example of these interdisciplinary contributions to the state of the art of optical amplification. Microresonators, interferometry, accuratemodeling, grating, nonlinear optics, and novel materials are the subjects included in the volume.
