   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quasi-phase matching; ferroelectric domains; stoichiometric LiNbO3; stoichiometric LiTaO3; KTiOPO4; KNbO3; polarization switching; periodic electric field poling; optical damages; Optical physics; Optisk fysik;

   Sammanfattning : Nonlinear optical frequency conversion is one of the most important key techniques in order to obtain lasers with wavelengths targeted for specific applications. In order to realize efficient and tailored lasers, the quasi-phase-matching (QPM) approach using periodically-poled ferroelectric crystals is getting increasingly important. LÄS MER

7. 20. Blue Laser Source for Laser-Induced Fluorescence

   Författare :Jesper Holm; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Second Harmonic Generation; Lasers; PPKTP; ALA; Tapered laser diodes; External cavity lasers; Laser-induced fluorescence; photodynamic therapy; mTHPC;

   Sammanfattning : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. LÄS MER
