  1. 1. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs

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

    Författare :Anna Brandt; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. LÄS MER

  3. 2. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    Magister-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Vidar Flodgren; [2019]
    Nyckelord :GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Sammanfattning : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. LÄS MER

  4. 3. Generation of tunable broadband deep ultraviolet radiation from gaseous media using ultrashort laser pulses.

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

    Författare :Esben Witting Larsen; [2011]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Most modern ultrafast lasers are based on mode-locked fiber or solid-state lasers and operate around the near infrared part of the electromagnetic spectrum. The widely spread CPA based Titanium Sapphire lasers can emit pulses centred around 800nm with durations down to 20 fs. LÄS MER
