The Development of Thulium and Holmium Fibre Sources

The Development of Thulium and Holmium Fibre Sources

Hosted By: Fiber Modeling and Fabrication Technical Group

30 September 2019, 8:00 - 9:00

Sources in the 1.9 - 2.1 um-spectral region are of interest for many applications including materials processing, optical communications, LiDAR, spectroscopy and various defence applications. Thulium and holmium fibres are an efficient and powerful scalable gain media that can address this spectral region. However, there are several challenges to address in order to realize this level of operation. In this webinar, hosted by the OSA Fiber, Modeling, and Fabrication Technical Group. Dr. Nikita Simakov of Defence Science and Technology Group (DST) will present onthe development of efficient fibres, waveguide designs in order to realize large-mode-area operation and non-linear mechanisms that arise from operating at this wavelength. Nikita will provide a review of recent power scaling experiments in literature and at the DST group.

What You Will Learn:

  • An appreciation of fibre compositions for achieving efficient operation in thulium and holmium
  • An understanding of relevant waveguide and fibre designs for thulium and holmium fibres
  • A review of non-linear effects that affects operation in this wavelength region
  • A review of power scaling experiments across the literature and at DST group in thulium and holmium fibre sources

Who Should Attend:

  • Undergraduate
  • Graduate Students (Master's and PhD)
  • Researchers (academics and industry)
