During Optics and Photonics in Sweden 2025 (OPS-2025) conference, awards were given 2025-10-23 to 1st and 2nd best Master Thesis, along with prizes for best student poster contributions.
PhotonicSweden’s award (1st prize) for the best master thesis in photonics/optics within the study year 2024/25 is given to Marzo López-Cerón for Master of Science Thesis performed at Lund University of Technology, and sponsored by Hamamatsu Photonics Norden AB. Maria Nilsson Tengelin handed over the prize for the Award Committee and Geethanjali Gopakumar represented Hamamatsu Photonics Norden AB.
“Design and implementation of an in-line imaging system and spectrometer for the single-shot grating dispersion scan technique for ultrafast pulse characterization”
This thesis demonstrates exceptional scientific creativity and technical accomplishment. It presents the design and realization of a novel single-shot dispersion-scan system capable of encoding significantly larger dispersion ranges, thereby enabling characterization of longer ultrashort pulses with remarkable simplicity. The results open new possibilities for practical applications in ultrafast optics, including nonlinear microscopy and laser-based material processing.
PhotonicSweden’s award (2nd prize) for an excellent master thesis in photonics/optics within the study year 2024/25 is given to Eleni Pefani for Master of Science Thesis performed at Lund University of Technology, and sponsored by Thorlabs Sweden AB. Maria Nilsson Tengelin handed over the prize for the Award Committee and Elin Eklund represented Thorlabs Sweden AB.
“A two-color interferometer for high-order harmonic generation”
The project involved the design and realization of a two-color interferometer for femtosecond pulses and a detailed study of third-harmonic generation from an Ytterbium laser system. Through both theoretical modeling and experimental investigation, the thesis achieved state-of-the-art conversion efficiencies and valuable insights into nonlinear and ultrafast optical processes.
