Course description

Fiber lasers have recently emerged as the technology of choice for a variety of industrial, scientific and defense applications. In this course, the fundamentals of fiber lasers will be taught interspersed with case studies into specific applications such as material processing, communications and defense. Given the fast-growing nature of this topic, the focus will be on depth in the basics and breadth in application domains.
