  1. 16. In-vivo study on the stability of the use of gas absorption spectroscopy as a technology for assessing sinus cavity size and oxygen gas concentration

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Sara Mekamy; [2020]
    Keywords : GASMAS; Sinuses; Stability measurements; Technology and Engineering;

    Abstract : Sinusitis is a common disease caused by a virus or bacteria, with 84% to 91% of cases caused by a viral pathogen. However, physicians prescribe antibiotics for this disease in 85% of all cases. READ MORE

  3. 17. Periodic and Non-Periodic Filter Structures in Lasers

    University essay from KTH/Matematik (Avd.)

    Author : Leo Enge; [2020]
    Keywords : Laser; Grating Filters; Perturbation Theory; WKB Approximation; Bi-cubic Splines; Laser; optiska filter; störningsteori; WKB-approximation; bi-kubiska splines;

    Abstract : Communication using fiber optics is an integral part of modern societies and one of the most important parts of this is the grating filter of a laser. In this report we introduce both the periodic and the non-periodic grating filter and discuss how there can be resonance in these structures. READ MORE

  4. 18. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Andre Nüsslein; [2019]
    Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

    Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE

  5. 19. Noncollinear optical parametric amplification of a supercontinuum

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

  6. 20. Temporal Characterization and Intensity Contrast Improvement of Few-cycle Laser Pulses

    University essay from Umeå universitet/Institutionen för fysik

    Author : Xiaoying Zhang; [2019]
    Keywords : ;

    Abstract : Due to the unique combination of properties of high intensity and few optical cycle pulse duration, the ultrashort laser pulses have widespread applications in pump-probe spectroscopy and laser-plasma interaction. Correspondingly, it is critical to precisely measure the electric field in the temporal or spectral domain. READ MORE
