Abstract

CUDNEY, R. S. et al. Fabricación de niobato de litio periódicamente polarizado para óptica no lineal. Rev. mex. fis. [online]. 2002, vol.48, n.6, pp.548-555. ISSN 0035-001X.

We describe how to produce periodically-poled lithium niobate (PPLN), which can be used to generate electromagnetic radiation of different frequencies through quasi-phase-matching. First we describe the basic principles of quasi-phase-matching and of ferroelectric crystals (which are used to obtain quasi-phase-matching), and then we give a detailed description of the fabrication process of PPLN. Using this technique we obtained PPLN samples over 5 cm long of high enough quality to obtain optical parametric generation through quasi-phase-matching.

Keywords : Quasi-phase-matching; optical parametric generation; second harmonic generation.
