Doctor Fiona M. Bain - Researcher

Fiona obtained her first degree in Physics B.Sc. (First Class hons) from the University of Wales, Aberystwyth in 2005. She then did her M.Sc. in Optics and Photonics at Imperial College, London which she completed in September 2006. She is now in the second year of her Ph.D. working in the Ultrashort-Pulse Laser Research Group. Fiona's current research involves investigating new Ytterbium doped laser crystals for highly efficient femtosecond lasers, and investigation of spectroscopic and laser related properties of crystalline thin film structures for optical waveguides.

Abstract: We demonstrate laser action in diode-pumped microchip monolithic cavity channel waveguides of Yb:KGd(WO4)2 and Yb:KY(WO4)2 that were fabricated by ultrafast laser writing. The maximum output power achieved was 18.6 mW with a threshold of approximately 100 mW from an Yb:KGd(WO4)2 waveguide laser operating at 1023 nm. The propagation losses for this waveguide structure were measured to be 1.9 dBcm−1.
