1. 21. Synchrotrons as a Source for Soft X-Ray Lithography

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

   Author : Thomas Joseph Grandsaert Jr; [2021]
   Keywords : Physics and Astronomy;

   Abstract : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

3. 22. Simulation of THz Quantum Cascade Lasers

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Viktor Rindert; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Quantum Cascade Lasers (QCLs) have since their invention in 1994 become a crucial source for mid-infrared and THz radiation. Mid-infrared QCLs have achieved room temperature operation while THz QCLs have not. As such, simulations are an important tool in order to achieve a THz QCL operational at room temperature.

4. 23. The visibility of double neutron star binaries to LISA

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Anatole Storck; [2021]
   Keywords : gravitational waves; LISA; neutron stars; orbital simulations; Runge-Kutta method; Physics and Astronomy;

   Abstract : Double neutron star binaries (DNSBs) in the mHz gravitational wave (GW) regime are an important group of objects which the GW detector LISA will be able to observe. The detection and parametrization of these objects will help develop our current understanding of neutron star formation and evolution. READ MORE

5. 24. Comparing the Effectiveness of Punching to Laser Cutting in UltraHigh Strength Steel

   University essay from KTH/Materialvetenskap

   Author : Felix Öhman; [2021]
   Keywords : ;

   Abstract : This study examines the efficiency of punching compared to laser cutting in sheets of Ultra High Strength Steel (UHSS). The study was conducted to determine which process is more efficient with respect to sheet thickness, where the quality of the cut edge is also taken into consideration of whether punching is recommended over laser cutting.

6. 25. 2D-material nanocomposites with nonlinear optical properties for laser protection

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Nils Ross; [2021]
   Keywords : optical power limiting; OPL; laser protection; nanocomposites; 2D-materials; graphene oxide; MXene; Ti3C2; melting gel; graphene; two-dimensional materials; nonlinear optical properties; NLO; spectroscopy;

   Abstract : 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. READ MORE
