  1. 1. Energy scaling of infrared nanosecond optical parametric oscillators and amplifiers based on Rb:KTiOPO4

    Författare :Riaan Stuart Coetzee; Valdas Pasiskevicius; Gunnar Rustad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : High-energy, narrowband, nanosecond pulsed mid-infrared sources centred on 2 μm are requiredin applications in remote sensing, standoff detection and pollution monitoring using LIDARs.Currently, space-borne LIDAR missions are under development by major space agencies aroundthe world for active measurements of the atmospheric gas constituents and their dynamics.

  3. 2. Nanosecond tandem optical parametric oscillators for mid-infrared generation

    Författare :Markus Henriksson; Fredrik Laurell; Gunnar Rustad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric oscillators; quasi-phase matching; mid-infrared; linewidth narrowing; volume Bragg gratings.; Physics; Fysik;

    Sammanfattning : This thesis discusses a new scheme for generating radiation in the mid infrared spectral region, especially the 3.5-5 µm range. The scheme uses established Nd3+-lasers at 1.06 µm and down conversion in nonlinear optical crystals. LÄS MER
