  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. Galaxy evolution in extreme environments

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Samhitha Vadlamani; [2019]
    Keywords : Galaxy evolution; interactions; starburst; Compact galaxy groups; Stephan s Quintet; Physics and Astronomy;

    Abstract : Interactions play a crucial role in determining how galaxies evolve in terms of their morphologies and star formation histories, since the majority of the known galaxies in the nearby Universe are found to exist in groups. Compact groups of galaxies are of particular interest as they contain a small number of galaxies in dense configurations and host repeated interactions between them, enabling us to capture signatures of these interactions (e.

  4. 13. 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

  5. 14. Optical Coherence Tomography measurements of biofibril dispersions in flow-focusing

    University essay from KTH/Mekanik

    Author : Cecilia Rydefalk; [2019]
    Keywords : ;

    Abstract : Microfluidic spinning techniques have been used as a successful assembly process for biofibrils dispersed in a fluid. The dispersion flows through a microchannel and is focused by a sheath flow. In this way the topology and velocity of the dispersion in the core can be manipulated. READ MORE

  6. 15. Implementation of High-Speed 512-Tap FIR Filters for Chromatic Dispersion Compensation

    University essay from Linköpings universitet/Datorteknik

    Author : Cheolyong Bae; Madhur Gokhale; [2018]
    Keywords : DSP; VHDL; FIR; Digital communication; Optical networks; Chromatic dispersion;

    Abstract : A digital filter is a system or a device that modifies a signal. This is an essential feature in digital communication. Using optical fibers in the communication has various advantages like higher bandwidth and distance capability over copper wires. READ MORE
