Periodically poled Crystal s are frequently used as Nonlinear Optical materials. They are up to 20 times more efficient at Second-harmonic Generation than crystals of the same material without Periodic structure. The material for the crystals is usually a wide Band Gap Inorganic crystal, or in some cases a suitable Organic Polymer . Some popular materials in current use are KTP , Lithium Niobate , and Lithium Tantalate . The periodic structure is created in the crystal using a range of techniques. Pulsed electric field, electron bombardment, thermal pulsing, or other methods can be used to reposition the Atom s in the Lattice , creating oriented domains. This can be achieved either during the growth of the crystal, or subsequently. {Link without Title} EXTERNAL LINKS |
