HARMONIC-GENERATION IN FERROELECTRIC LIQUID-CRYSTALS - PHASE-MATCHINGLOCI

Ferroelectric liquid crystals (FLCs), a new class of organic nonlinear materials have a variety of interesting properties and potential appl ications. Using commercial FLCs and an FLC mixture specifically formul ated for enhanced nonlinear optical properties, we studied the room-te mperature global phase-matching properties for type I and type II freq uency doubling of 1.06-mum radiation. Although the second-harmonic coe fficients of the different FLC mixtures differ by as much as two order s of magnitude, the phase-matching loci are remarkably similar.
