Tailoring performance of ultrafast fibre lasers for applications in surgery and diagnostics

Leibniz Institute of Photonic Technology / Jena, Germany

Ultrashort pulse laser systems are versatile tools for variety of applications and particularly demonstrate high potential for operating as multi-functional instruments for combined diagnostics and therapy, primarily surgery. High peak power of ultrafast fibre lasers is ideally suited for ablation of tissues with different densities. At the same time recently established real-time methodologies to evaluate spectra of individual ultrashort pulses has paved a way for novel direct ultrafast spectroscopy and imaging techniques for diagnostics.

Current limitations for wide application of lasers for healthcare are set due to complexity and size of laser systems and necessity to tailor parameters of laser generation to particular function. In the presentation I will give an overview of novel approaches for substantial power scaling, expansion towards new wavelength ranges and obtaining special lasing generation regimes. I will provide preliminary data of translating ultrafast fibre laser technology to area of therapy and diagnostics.

Short Bio

Maria Chernysheva obtained her PhD degree in Laser Physics from Fiber Optics Research Center of the Russian Academy of Sciences in 2014. Shortly after she moved to UK where she worked at Aston University as Research Fellow. Maria has won two highly competitive and prestigious Fellowships in two years: Marie Skłodowska-Curie Individual Fellowship (EU Horizon2020) and Engnineering for Development Research Fellowship from Royal Academy of Engineering and Global Challenges Research Fund. Starting from beginning of 2019 she has been a leader of Junior Research Group “Ultrafast fibre lasers” at Leibniz Institute of Photonic Technology (Jena, Germany).
