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/AtomfysikAbstract : 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

2. 2D-material nanocomposites with nonlinear optical properties for laser protection
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Lasers are increasingly used for a wide range of different applications for both civil and military purposes. Due to the distinct properties of laser light, use of lasers often comes with a risk of damage to the human eye and other optical sensors. Therefore, an effective laser protection is needed.

3. Noncollinear optical parametric amplification of a supercontinuum
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : 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

4. The Spatial Properties of the Beam Profile of an OPCPA
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikAbstract : 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.

5. Temporal Characterization and Intensity Contrast Improvement of Few-cycle Laser Pulses
University essay from Umeå universitet/Institutionen för fysikAbstract : Due to the unique combination of properties of high intensity and few optical cycle pulse duration, the ultrashort laser pulses have widespread applications in pump-probe spectroscopy and laser-plasma interaction. Correspondingly, it is critical to precisely measure the electric field in the temporal or spectral domain. READ MORE
