  3. 2. Continuously tunable narrow-linewidth fiber lasers

    Författare :Xiong Yang; Valdas Pasiskevicius; Fredrik Laurell; Magnus Engholm; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber laser; Optik och fotonik; Optics and Photonics;

    Sammanfattning : Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber lasers. LÄS MER

  4. 3. Compact diode-pumped solid-state lasers

    Författare :Stefan Spiekermann; KTH; []
    Nyckelord :visible lasers; UV lasers; solid-state lasers;

    Sammanfattning : 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. LÄS MER

  5. 4. Semiconductor Lasers with Gratings Defined by Electron Beam Lithography

    Författare :Torgil Kjellberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lasers; field-stitching errors; single-mode stability; fiber-optic communication;

    Sammanfattning : This thesis deals with the fabrication and characterization of semiconductor lasers with gratings defined by electron-beam lithography (EBL). Both distributed-feedback (DFB) lasers for fiber-optic communication and grating-surface-emitting (GSE) lasers suitable for a number of novel applications, from free-space communication to optical processing, are treated.

  7. 5. All-fiber modulators for laser applications

    Författare :Mikael Malmström; Fredrik Laurell; Simon Fleming; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; All-fiber; fiber optics; modulation; q-switching; mode-locking;

    Sammanfattning : The objective of this thesis was to explore the usefulness of all-fiber modulators for laser applications. The modulators were all based on refractive index change achieved in the core of the studied fiber- components, exploiting either the elasto-optic effect or the electro-optic effect. LÄS MER
