  1. 1. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

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

    Author : Axel Elfving; [2019]
    Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Abstract : 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

  2. 2. 3D Finite Element Modelling of ICRH in JET

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Björn Ljungberg; [2019]
    Keywords : ;

    Abstract : This master's thesis assesses the possibility of using the nite element method to solve the electromagneticwave equation in a fusion plasma in 3D. In particular, the frequency is chosen to match that of ioncyclotron resonance heating in the fusion experiment JET. READ MORE

  3. 3. On two-component Bose-Einstein condensates in a ring

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Marcus Sköld; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : A Bose-Einstein condensate is a type of gas consisting of one or more types of particles called bosons which are cooled to a temperature very close the absolute zero. Under these conditions the particles all start to occupy their lowest quantum state. READ MORE

  4. 4. Noncollinear optical parametric amplification of a supercontinuum

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

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE


    University essay from KTH/Industriell ekonomi och organisation (Inst.)

    Author : AMINA SHAHIN; [2018]
