  1. 1. Pulse Compression of Short Wavelength Infrared Optical Parametric Amplified Pulses Using a Hollow Core Capillary

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

    Author : Neven Ibrakovic; [2015]
    Keywords : HHG; pulse compression; HCF; KDP; Dispersion; few cycle; TOPAS; OPA; Nonlinear; anomalous dispersion; waveguide; Physics and Astronomy;

    Abstract : In this thesis, a method for producing few-cycle short wavelength infrared pulses is presented. The pulses are created by down converting the 800 nm output of a Ti:Sapphire laser in an optical parametric amplifier to 1300 nm, and spectrally broadened in a hollow core fiber in order to obtain a short transform limited pulse duration.

  3. 2. Quantitative analysis of multi-phase systems -steels with mixture of ferrite and austenite

    University essay from Institutionen för fysik, kemi och biologi

    Author : Salman Kohar Fawad; [2004]
    Keywords : Physics; Quantitative analysis; X-ray powder diffraction; Electron backscatter diffraction; Magnetic balance; Topas; Austenite and Ferrite steels.; Fysik;

    Abstract : The goal of this work has been to evaluate the different experimental techniques used for quantitative analysis of multi-phase materials systems. Powder based specimens containing two-phases, austenite and ferrite , were fabricated and quantified. The volume fraction of ferrite varied from 2 Vol% to 50 Vol%. READ MORE

  4. 3. Introduction of New Technique in Argentina : Multimedia in training & Education.

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

    Author : Håkan Söderstedt; Ingemar Sekund; [1992]
    Keywords : Technology and Engineering;

    Abstract : We have searched for different possibilities to introduce Multimedia at a welding company in Argentina. We decided to create a training system. Our system should teach an unskilled user how to use a rather camplex expert system for welding. In this paper we discuss the design and implementation of a multimedia training system. READ MORE
