Fiber Lasers
Fluoride is the New Silica: Unlocking the Mid-IR Frontier in Fiber Lasers:
While only a handful of mid-IR laser technologies have matured beyond 2.5 μm, fibre lasers are rapidly emerging as a compelling platform for high-brightness mid-IR sources, opening new possibilities for a wide range of applications. This talk will focus on the properties and design potential of fluoride-based optical fibres, recent advances in their functionalisation, and evolving strategies for component fabrication and post-processing. The talk will highlight the current state of the field and outline directions for future development in mid-IR fibre laser technologies.
Spectral and Temporal Versatility of Fiber-Based Laser Sources:
This talk will explore the evolving strategies for shaping ultrashort pulses in fibre laser systems. Beginning with conventional mode-locking schemes, the discussion will quickly move toward emerging approaches that bypass traditional saturable absorbers, highlighting instability-driven dynamics and the formation of coherent structures and self-organization. On the spectral side, the talk will examine the range of available and emerging rare-earth gain media, with special attention given to how new gain materials can extend the operational window of fibre lasers into spectral regions of growing relevance for sensing, imaging, and nonlinear optics.
About the Speaker
Maria Chernysheva received her PhD in Laser Physics in 2014 from the Fiber Optics Research Center of the Russian Academy of Sciences. She then continued her research at Aston University, UK, supported by two consecutive individual fellowships: the Marie Skłodowska-Curie Fellowship and the Royal Academy of Engineering Research Fellowship. In 2019, she moved to Germany to establish her own research group at the Leibniz Institute of Photonic Technologies. Her work focuses on ultrafast nonlinear optics, fibre lasers at emerging wavelengths, and shaping the dynamics of ultrashort pulses. Maria currently serves as a topical editor for Optics Letters and was Program Chair of the CLEO 2025 conference.
