Seminar by Dr. Maria Chernysheva (Leibniz Institute of Photonic Technologies, Germany – EMIMEP Associated partner)
Dr. Maria Chernysheva (Leibniz Institute of Photonic Technologies, Germany – EMIMEP Associated partner) delivered two seminars on October 23rd, 2025.
Abstract.
First seminar (1 hour). Optical fibre and waveguide materials
Since the very first demonstration, fibre lasers have rapidly developed into a compelling platform for high-brightness light sources, opening new possibilities for a wide range of applications. This lecture will focus on the properties and design potential of modern optical fibres and waveguides, recent advances in their functionalisation, and evolving strategies for fibre and waveguide-based component fabrication and post-processing. The talk will highlight the current state of the field and outline directions for future development in laser technologies.
Second seminar (1 hour). 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 move toward emerging approaches that bypass traditional saturable absorbers for the formation of coherent structures and self-organisation. On the spectral side, the lecture will present the range of available and emerging rare-earth gain media, with a 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.
Bio.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.
