1. 1. Strain/Stress profile investigation of crystals mounted in an optical instrument via FEM simulation

   University essay from Lunds universitet/Industriell Produktion

   Author : Matheus Amarante Machado; [2023]
   Keywords : Modeling; Abaqus; Y2SiO5; Finite Element Modeling; Strain; Stress; Yttrium Orthosilicate.; Technology and Engineering;

   Abstract : Abstract This work is one of a series of related papers that were made in Lund University. They were done to analyze in a multi scalar way the Yttrium Orthosilicate crystals (YSO), analyzing the variation of material properties stemmed from the mounting, composition and other parameters in the optical properties of Yttrium Orthosilicate crystals.

3. 2. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal

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

   Author : Antonius Johannes Renders; [2023]
   Keywords : Fast Light; Superluminal Propagation; Negative group velocity; Rare earth; Physics and Astronomy;

   Abstract : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. READ MORE

4. 3. Magnificent beasts of the Milky Way: Hunting down stars with unusual infrared properties using supervised machine learning

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Julia Ahlvind; [2021]
   Keywords : machine learning; supervised machine learning; support vector machine; photometry; stars; stellar physics; astronomical archives;

   Abstract : The significant increase of astronomical data necessitates new strategies and developments to analyse a large amount of information, which no longer is efficient if done by hand. Supervised machine learning is an example of one such modern strategy. READ MORE

5. 4. Single Ion Detection of Cerium in Y2SiO5 Microcrystals

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

   Author : Vassily Kornienko; [2019]
   Keywords : cerium; YSO; rare-earths; quantum computing; microcrystals; Physics and Astronomy;

   Abstract : Quantum computing with single instances of rare earth-ions doped into inorganic crystals shows great promise as a scalable design in the field of quantum information. A detectable and controllable single readout ion is necessary for the scheme proposed in Lund to work. READ MORE

6. 5. Investigation of phase conjugation for medical imaging

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

   Author : Ivan Sytcevich; [2017]
   Keywords : Phase conjugation; Ultrasound Optical Tomography; Rare-Earth-Doped Crystals.; Physics and Astronomy;

   Abstract : With the development of extremely precise spectral filters based on spectral hole burning and slow light effects, the idea of their implementation in an Ultrasound Optical Tomography (UOT) medical imaging technique arose. Simulations have shown that the resulting Contrast-to-Noise (CNR) ratio is fairly good at depths up to 5 cm but decreases dramatically when probing deeper in tissue. READ MORE
