  1. 11. 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

  3. 12. The Spatial Properties of the Beam Profile of an OPCPA

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

    Author : Mattias Bengtsson; [2019]
    Keywords : Laser; OPCPA; Imaging Spectrometer; Physics and Astronomy;

    Abstract : OPCPA stands for optical parametric chirped-pulse amplification. It is a nonlinear method for amplifying broadband laser beams. The spatial properties of the output of the laser beam depends on the amplification method itself and the broadband configuration. READ MORE

  4. 13. Förekomst av B- och T-lymfocyter i hypofysen hos hund

    University essay from SLU/Dept. of Clinical Sciences

    Author : Marcus Blomqvist; [2018]
    Keywords : hypofysit; hypofys; hund; lymfocyt; CD3;

    Abstract : The pituitary gland, or hypophysis, is often referred to as the ”master gland”. It controls the production and secretion of hormones by peripheral endocrine glands. The pituitary gland is situated ventral to the hypothalamus in the hypophyseal fossa. Hypophysitis, i. READ MORE

  5. 14. The Supply and Demand of Peace

    University essay from Lunds universitet/Statsvetenskapliga institutionen

    Author : Anton Juggas Öberg; [2017]
    Keywords : Neoliberalism; hegemony; critical theory; marketization; peacebuilding.; Social Sciences;

    Abstract : The purpose of this essay was to examine the structural composition of the global hegemony, and how it was expressed in peace building in Iraq. In order to examine this, the neoliberal hegemony was outlined with the help of Rovert Cox’s notions of structures and other critical scholars’ notions of neoliberalism. READ MORE

  6. 15. Analysis and simulation of centrifugal pendulum vibration absorbers

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Emma Smith; [2015]
    Keywords : CPA; Adams Car; drivetrain simulations; epicycloid; tuning;

    Abstract : When environmental laws are constricted and downsizing of engines has become the reality of the vehicle industry, there needs to be a solution for the rise in torsion vibrations in the drivetrain. These increased levels of torsion vibrations are mostly due to excitations from the firing pulses, which in turn have become increased due to higher cylinder pressures. READ MORE
