  7. 10. Optical parametric amplification with periodically poled KTiOPO4

    Författare :Anna Fragemann; Fredrik Laurell; Ebrahim-Zadeh Majid; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric amplification; optical parametric generation; optical parametric oscillation; Optical physics; Optisk fysik;

    Sammanfattning : This thesis explores the use of engineered nonlinear crystals from the KTiOPO4 (KTP) family as the gain material in optical parametric amplifiers (OPAs), with the aim to achieve more knowledge about the benefits and limitations of these devices. The work aims further at extending the possible applications of OPAs by constructing and investigating several efficient and well performing amplifiers. LÄS MER
