1. Simulation of Quantum Cascade Lasers
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

2. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : 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. READ MORE

3. None are so deaf as those who would not hear : identifying where, who, and how the coal industry influences Australian federal energy policies
University essay from Lunds universitet/LUCSUSAbstract : The widespread consequences of climate change are becoming more and more evident around the world and are raising crucial awareness to world leaders that a sustainable transition is direly needed to mitigate against disastrous climatic events. In Australia, in early 2020, these events took the form of some of the most devastating and largest forest fires the country has ever seen. READ MORE

4. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE

5. Temporal Characterization and Intensity Contrast Improvement of Few-cycle Laser Pulses
University essay from Umeå universitet/Institutionen för fysikAbstract : Due to the unique combination of properties of high intensity and few optical cycle pulse duration, the ultrashort laser pulses have widespread applications in pump-probe spectroscopy and laser-plasma interaction. Correspondingly, it is critical to precisely measure the electric field in the temporal or spectral domain. READ MORE
