I will first briefly introduce the notions and technological milestones that improved the early fiber lasers up to their generalized use in recent years, from the research lab to the industry. Then, I will focus on the generation of short and ultrashort pulses from fiber lasers. The fiber cavity medium involves in general a substantial participation of nonlinear and dispersive effects. That is why soliton concepts have been closely related from the beginning to mode-locked fiber laser operation. I will show how the goings and comings between experiments and theoretical considerations have made these concepts evolve, toward the generalized notion of a dissipative soliton, which also made scientists move beyond conventional laser stereotypes.
Philippe Grelu has been professor of physics and photonics at Université de Bourgogne (Uni. of Burgundy) in Dijon since 2005. After a PhD in quantum optics in 1996, his interests moved to ultrafast nonlinear optics and mode-locked fiber lasers. Philippe has promoted the usage of dissipative solitons to discover and interpret original laser dynamics. With his close collaborators, he introduced artificial intelligence to pilot ultrafast fiber lasers. He has authored over 200 publications in journals and proceedings.
