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

    University dissertation from Stockholm : Fysik

    Author : Stefan Spiekermann; KTH.; [2004]
    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

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

    University dissertation from Stockholm : KTH

    Author : Sandra Johansson; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; frequency conversion; visible lasers; ultraviolet lasers; KTiOPO4; BiBO; BBO; quasi phase-matching; birefringent phase-matching; solid-state lasers; NATURAL SCIENCES Physics; NATURVETENSKAP 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.

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

    University dissertation from Stockholm : KTH

    Author : Jonas Hellström; KTH.; [2007]
    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; NATURAL SCIENCES Physics; NATURVETENSKAP 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

  4. 4. Thermal properties of volume Bragg gratings and its implications on lasers

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Staffan Tjörnhammar; KTH.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermal effects; Volume Bragg Gratings; VBG; Lasers;

    Abstract : This thesis contains the results of research on the spectral control of lasers, specifically, the thermal limitations of volume Bragg gratings (VBGs), employed as laser-cavity end mirrors. The investigations consisted of both experiments and numerical simulations. READ MORE
