  1. 16. Near-infrared optical frequency comb Vernier spectroscopy in air and in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Maryam Fakhri; [2017]
    Keywords : ;

    Abstract : A Vernier spectrometer is built with a near-infrared mode-locked Er:doped fiber laser, a Fabry-Perot cavity with finesse of 1000, a diffraction grating and a photo detector. The optical cavity provides high sensitivity in absorption detection by enhancing the interaction length of the light with molecular species contained in the cavity. READ MORE

  3. 17. Implementation of continuous filtering frequency comb Vernier spectroscopy for continuous acquisition of spectra in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adam Edlund; [2017]
    Keywords : optical frequency comb; continuous filtering Vernier spectroscopy;

    Abstract : In this project laser absorption spectroscopy was performed on a flame in a Fabry-Pérot cavity, using an optical frequency comb. Optical frequency comb spectroscopy is a technique that allows broadband ultra-sensitive detection of molecular species in gas phase. READ MORE

  4. 18. Semi Solid Metal Casting : Study Of Slurry Preperation Parameters

    University essay from Högskolan i Jönköping/JTH, Maskinteknik

    Author : Niclas Rothén; Jacob Aho; [2017]
    Keywords : Slurry; EEM; Primary α-Al; primary alpha alumnium; semi solid casting; SSM; growth layer; Rheometal;

    Abstract : This thesis work is an experimental study of one type of Semi-Solid Metal casting (SSM) process which is called RheoMetalTM. This method is an efficient type of Rheocasting that creates a semi-solid slurry within 30 seconds that is used for a high pressure die casting machine. READ MORE

  5. 19. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysik

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

    Abstract : 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. READ MORE

  6. 20. Optical Fiber Phase Noise Cancellation for Slow Light Crystal Cavity Locking

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

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

    Abstract : 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.
