  1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ibtisam Dahir Ahmed; [2023]
    Nyckelord :Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Sammanfattning : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. LÄS MER

  3. 2. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Berkay Efilti; [2023]
    Nyckelord :Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

    Sammanfattning : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

  4. 3. Modeling a Tunable Narrow Linewidth Laser

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Christoffer Ejemyr; [2020]
    Nyckelord :Laser; Tunable; Model; Lasing frequency; DBR;

    Sammanfattning : In this report a model of a tunable narrow linewidth laser used for telecommunications is presented. The model uses both theoretical analysis and experimental data to create the mathematical models governing its behaviour and is aimed to be useful in a development environment with requirements on accuracy, efficient implementation and adaptability to future design.

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

    Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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. LÄS MER

  7. 5. Single Ion Detection of Cerium in Y2SiO5 Microcrystals

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Vassily Kornienko; [2019]
    Nyckelord :cerium; YSO; rare-earths; quantum computing; microcrystals; Physics and Astronomy;

    Sammanfattning : Quantum computing with single instances of rare earth-ions doped into inorganic crystals shows great promise as a scalable design in the field of quantum information. A detectable and controllable single readout ion is necessary for the scheme proposed in Lund to work. LÄS MER
