1. 1. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique

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

   Author : Daniel Díaz Rivas; [2022]
   Keywords : pulse characterisation; ultrashort; laser; femtosecond; dispersion scan; polarisation; wave plate; temporal reconstruction; electric field reconstruction; time-dependent polarisation; polarisation gate; Physics and Astronomy;

   Abstract : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. READ MORE

3. 2. Characterisation of a New Type of Solid Organic Scintillator for neutron-gamma Discrimination using Pulse-Shape DiscriminationTechniques

   University essay from Uppsala universitet/Kärnfysik

   Author : Qadir Nishada; [2014]
   Keywords : EJ-299-33; PSD; Pulse-shape discrimination; plastic scintillator; neutron-gamma discrimination; scintillator decay times;

   Abstract : In this report the neutron-gamma discrimination capabilities of the new type of solid organic scintillator, EJ-299-33, was investigated using several pulse-shape discrimination (PSD) techniques. Among others, the analog zero-crossing method andthe digital charge-comparison and integrated-rise-time method were tested. READ MORE
