    Abstract : This thesis deals with the fabrication and the characterization of periodically-poled crystals for use in lasers to generate visible and UV radiation by second-harmonic generation (SHG) through quasi-phasematching (QPM). Such lasers are of practical importance in many applications like high-density optical storage, biomedical instrumentation, colour printing, and for laser displays. READ MORE

  4. 2. Fabrication of periodically poled crystals from the KTP family and their applications in nonlinear optics
