  1. 1. 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

  2. 2. Incoherent Scattering of Twisted Radar Beams from the Ionosphere

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Viktor Lannér; [2017]
    Keywords : ionosphere; plasma; twisted beams; orbital angular momentum; oam effects;

    Abstract : In the search for natural orbital angular momentum (OAM) effects, some of the first incoherent scatter experiments with twisted radar beams during aurora were conducted at Poker Flat Incoherent Scatter Radar (PFISR), Alaska, USA, in October 2012. Experimental data of scatter from beam configurations with opposite twists were investigated. READ MORE

  3. 3. Design of Industrial Floors: Principles for Control of Warping.

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Mohammed Ali Alhasani; Ahmed Zaraei; [1996]
    Keywords : Technology and Engineering;

    Abstract : The Slab-on-grade, which include Industrial floors, can be defined, according to ACI Committee 360,1 as a slab continuously supported by ground with an area of more than twice the area required to support the imposed loads. The slab may be plain or reinforced and may include stiffening elements such as ribs and hidden beams. READ MORE
