  1. 1. 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.

    Sammanfattning : In the realm of neuroelectronics, the challenge lies in achieving finer observations of physiological processes to comprehend neuronal interactions and computations. This necessitates the development of more compliant and biomimetic interfaces for improved integration with biological tissues, enabling finer physiological process observations. LÄS MER

  4. 3. Phase-Contrast Imaging, Towards G2-less Grating Interferometry With Deep Silicon

    Master-uppsats, KTH/Fysik

    Författare :Rickard Brunskog; [2022]
    Nyckelord :Phase-contrast imaging; phase-contrast; CT-scanning; Computed-tomography; 1 micrometer resolution x-ray; grating-less phase-contrast imaging; Faskontraströntgen; faskontrast; CT-skanning; 1 mikrometer upplösning x-ray; gitterlös faskontrast; datortomografi;

    Sammanfattning : Conventional phase-contrast imaging entails stepping an analyser grating across the detector to resolve the interference pattern caused by the x-rays after passing through a series of gratings in a so-called Talbot-Lau interferometer. However, the analyser grating in the interferometer poses a challenge, not only due to the machinery and alignment required but also due to each exposure delivering a dose to the subject. LÄS MER

  5. 4. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Colin Carlile; [2021]
    Nyckelord :Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

    Sammanfattning : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. LÄS MER

  7. 5. Design of a Temperature Insensitive Fiber Interferometer for Long-Term Laser Frequency Stabilization using Metal Coated Fibers

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

    Författare :Saskia Bondza; [2019]
    Nyckelord :laser frequency stabilization; fiber interferometer; thermal sensitivity; optical fibers; drift-free; aluminum coated; thermal stress; Physics and Astronomy;

    Sammanfattning : This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this purpose, single acrylate, dual acrylate, copper and aluminum coated bers are analyzed theoretically and experimentally regarding the thermal sensitivity of their optical path length. LÄS MER
