2. 1. Compact diode-pumped solid-state lasers

   Author : Stefan Spiekermann; KTH; []
   Keywords : visible lasers; UV lasers; solid-state lasers;

   Abstract : Compact diode-pumped solid-state lasers (DPSSL) arecontinuously replacing traditional gas lasers as well asenabling completely new technology. However, compact and costefficient designs are required to satisfy end-user demands. Theaim of this thesis was therefore to investigate novel laserdesigns for given applications considering these demands. READ MORE

4. 2. Concepts for compact solid-state lasers in the visible and UV

   Author : Sandra Johansson; Fredrik Laurell; Patrick Georges; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; frequency conversion; visible lasers; ultraviolet lasers; KTiOPO4; BiBO; BBO; quasi phase-matching; birefringent phase-matching; solid-state lasers; Physics; Fysik;

   Abstract : In many fields, scientific or industrial, optical devices that can be tailored in terms of spectral qualities and output power depending on the application in question are attractive. Nonlinear optics in combination with powerful laser sources provide a tool to achieve essentially any wavelength in the electromagnetic spectrum, and the advancement of material technology during the last decade has opened up new possibilities in terms of realising such devices.

5. 3. On diode-pumped solid-state lasers

   Author : Jonas Hellström; Fredrik Laurell; Valdas Pasiskevicius; Klaus Petermann; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; near-infrared lasers; end-pumped lasers; Q-switching; erbium; ytterbium; GdCOB; KGW; KYW; Co:MALO; laser materials; thermal lensing; end-pumping; spectroscopy; conical refraction; volume Bragg gratings; holographic gratings; laser tuning; Physics; Fysik;

   Abstract : The research that is presented in this thesis can be divided into two major parts. The first part concerns longitudinally pumped, bulk Er-Yb lasers. In these lasers, the main limitation is the thermal shortcomings of the phosphate glass host material. READ MORE

6. 4. Novel Technologies for Mode-Locking of Solid-State Lasers

   Author : Niels Meiser; Valdas Pasiskevicius; Steinmeyer Günter; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser; mode-locked laser; pulsed laser; quantum dot; carbon nanotube; nonlinear optics; saturable absorber; Kerr-lens mode-locking; ultra-fast laser; picosecond laser; pulsed laser; semiconductor saturable absorber;

   Abstract : The subject of this thesis is the investigation of novel technologies for mode-locking of diode-pumped, solid-state lasers. Novel saturable absorbers are used: quantum dots (QDs) and carbon nanotubes (CNTs), which both are low-dimensional nano-formations. In addition, mode-locking by cascaded nonlinearities is explored.

7. 5. Compact solid-state lasers in the near-infrard and visible spectral range

   Author : Kai Seger; Fredrik Laurell; Uwe Griebner; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; volume Bragg gratings; single-longitudinal-mode laser; laser tuning; Q-switching; mode-locking; carbon nanotubes; semiconductor lasers; neodymium; ytterbium; nonlinear optics; KTP;

   Abstract : The subject of this thesis is the exploration of new concepts for compact solid-state lasers in the visible and near-infrared spectral range using new components such as volume Bragg gratings for wavelength stabilisation and wavelength tuning. Also single-walled carbon nanotubes for mode-locking and Q-switching of lasers have been studied. READ MORE
