  1. 6. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysik

    Författare :Alexander Bengtsson; [2017]
    Nyckelord :Optical Fibers; Fiber Noise Cancellation; Laser Stabilization; Slow Light Laser Locking; Technology and Engineering;

    Sammanfattning : An electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. LÄS MER

  3. 7. Development of a Tunable Frequency Shift Filter Using a Praseodymium Doped Y2SiO5-Crystal

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Yupan Bao; [2016]
    Nyckelord :Ultrasound Optical Tomography UOT ; Off-resonant Slow Light; Filter; Frequency Shifter; Spectral Hole Burning Technique; Rare-earth-ion-doped Crystal; Physics and Astronomy;

    Sammanfattning : In this thesis, a tunable frequency shift filter (FSF) with a 1 ~ 2 MHz passband created in a praseodymium doped Y2SiO5-crystal using a special hole burning technique is developed and tested. The FSF is able to shift the frequency of its passband and the light passing through the passband by applying an external electric field, where the frequency shift is proportional to the applied field.

  4. 8. Optical Fiber Phase Noise Cancellation for Slow Light Crystal Cavity Locking

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

    Författare :Mohammad Tasnimul Haque; [2016]
    Nyckelord :Optical Fiber; Phase Noise; Slow Light; Stabilisation; Quantum Information; Quantum Optics; Optical Clocks; Physics and Astronomy;

    Sammanfattning : Recent developments in the field of optical clocks and quantum information have fueled the necessity for both fiber phase noise cancellation and laser stabilisation. The Quantum Information group at Lund University is conducting research on quantum computation experiments based on rare earth ion doped crystals and also application of slow light effects induced by spectral hole burning in these rare earth ion doped crystals.

  5. 9. Parameter study of a muffle furnace performance on powder heating using numerical multiphysics simulation with COMSOL

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Emil Stålnacke; [2015]
    Nyckelord :muffle furnace; syngas; biomass; natural gas; parameter study; comsol; powder metallurgy; heat transfer;

    Sammanfattning : The muffle furnace main purpose is to anneal the rough sponge iron powder transported through it, which is done by burning natural gas. Heat is absorbed by the muffle and is transferred to the bed of sponge iron powder. LÄS MER

  7. 10. Investigation and evaluation of potential exhaust braking strategiesusing model predictive control

    Master-uppsats, KTH/Reglerteknik

    Författare :Erik Hallqvist; [2015]
    Nyckelord :;

    Sammanfattning : The eciency of today's aftertreatment system relies on the exhaust gas temperature.The Selective Catalytic Reduction system, which is a part of theaftertreatment system has an operating temperature window which starts atapproximately 200C in order to work as eciently as possible.
