AI Article Synopsis
- The report discusses the generation of second harmonics in Lithium Tantalate through a method called random Quasi-Phase-Matching.
- By analyzing far-field profiles at different wavelengths, researchers gather statistical data on the quadratic nonlinearity's distribution and average period in both the surface and bulk of the material.
- The study provides a non-invasive technique to investigate the poling dynamics by comparing these distributions in the two regions.
Article Abstract
We report on bulk and guided-wave second-harmonic generation via random Quasi-Phase-Matching in Lithium Tantalate. By acquiring the far-field profiles at several wavelengths, we extract statistical information on the distribution of the quadratic nonlinearity as well as its average period, both at the surface and in the bulk of the sample. By investigating the distribution in the two regions we demonstrate a non-invasive approach to the study of poling dynamics.
